APIBridge for Elementor: Documentation

Connect any JSON API to your WordPress site and show its data with Elementor widgets. No coding needed. This guide shows you how, step by step.

What it does

An API is a web address that gives you data, for example today's weather, a product list or a currency rate. The data usually comes in a format called JSON.

APIBridge fetches that data on your server and lets you place it anywhere on your page using Elementor widgets. You do three things:

  • Save the API address once, as a connection.
  • Drag an APIBridge widget onto your page.
  • Pick which piece of data the widget should show.

Your visitors never see the API address or your API key. Everything is requested by your own server.

What you need

  • WordPress 6.0 or newer, and PHP 7.4 or newer.
  • The Elementor plugin. The free version is enough. You do not need Elementor Pro.
  • The address (URL) of the API you want to use. Its own documentation page usually tells you this, plus whether you need a key.

Quick start

This takes about five minutes. You will connect an API and show one value from it.

  1. Install and activate In WordPress go to Plugins → Add New, search for APIBridge for Elementor, then click Install Now and Activate. If you have the plugin as a zip file, use Upload Plugin instead.
  2. Add a connection Open APIBridge → API Connections and click Add New. Give it a name and paste the API address. Details are in Every field explained.
  3. Test it Click Test Connection. You will see every piece of data the API returns. If you see data, the connection works. Click Save connection.
  4. Add a widget Edit a page with Elementor. In the widget panel, open the APIBridge group and drag API Headline onto the page.
  5. Choose the data In the widget, pick your connection, then pick a field with Pick from live data (or type its path). The value appears right away. Click Publish.

TipStart with an API that needs no key, so you can learn the steps first. Add keys and visitor input later.

Create a connection

A connection tells APIBridge where your data comes from. You create it once and can then use it in as many widgets as you like. There is no limit on how many connections you can add.

Go to APIBridge → API Connections and click Add New. The form has these parts, from top to bottom:

  1. Basics: name, address and method.
  2. Authentication headers: an API key, if the API needs one.
  3. Does this API need input from your visitor?
  4. Caching: how long to remember results.

Every field explained

1. Basics

FieldWhat to enter
Connection nameA label only you see, for example Weather API. You will pick the connection by this name in Elementor.
Endpoint URLThe full web address of the API. If the API allows it, send your key in a header (next part) instead of putting it in the URL.
Request methodGET for most APIs that only give you data. Choose POST only if the API documentation tells you to.

2. Authentication headers (optional)

Many APIs ask for a key or token. Click Add header and fill in two boxes:

Header nameFor example Authorization
Header valueFor example Bearer your-token

The value is stored encrypted and is never shown again after you save. To change it, type the new value over the saved one. Use Remove to delete a header.

3. Does this API need input from your visitor?

Choose the option that fits.

OptionWhen to use it
No input neededThe API returns data by itself, for example a list of today's offers.
Input requiredThe visitor must type something first, for example a city, an email address or a domain name.

If you chose No input needed, one more question appears:

When should the data load?What happens
Load on page viewThe data loads automatically when the page opens.
Load on button clickThe visitor clicks a Load/Refresh button to get the data.

If you chose Input required, you will see these fields instead:

FieldWhat to enter
Parameter nameThe name the API expects, written exactly as in its documentation. For example q, city or domain.
Send the value inThe URL (query string) for most APIs. Choose The request body (POST only) only if the API documentation says so.
Body formatOnly used when sending in the body. JSON suits most modern APIs. Choose Form data if the documentation asks for it.
Expected value typeWhat your visitor will type: Text, URL / domain, Email address, Number or Anything. APIBridge checks the input against this and shows the right keyboard on phones.
Value for Elementor (optional)Elementor has no visitor to ask, so its field picker uses this value to fetch sample data. Type a real example, such as an existing city name. Leave it empty if you only use this connection in the APIBridge widgets.

4. Caching

Remember successful results forChoose Do not cache, 30 seconds, 1 minute, 5 minutes, 15 minutes or 1 hour. Caching saves your API quota and makes busy pages faster. Only successful results are remembered, never errors. Choose Do not cache if the data must always be live.

When you are done, click Save connection.

Test Connection

At the bottom of the form, Test Connection sends a real request using the settings above. You do not need to save first.

  • If the connection needs visitor input, type an example into Sample value for the test first.
  • You will see every field the API returns, so you know exactly what to choose in your widgets.
  • Click Copy path next to any field, then paste it into a widget.

If the test failsCheck the address for typing mistakes, check that the key is correct, and check that the method (GET or POST) matches the API documentation. See Fixing problems.

JSON field path

A path tells a widget which piece of the data to show. You write it with dots, from the outside in. In most cases you do not need to type it: use Pick from live data in the widget, or Copy path on the Test Connection screen.

Here is an example of data from an API. Each coloured piece matches one path in the table below it.

{
  "title": "Pocket Guide to Lucknow",
  "user": {
    "name": "Asha",
    "address": { "city": "Lucknow" }
  },
  "items": [
    { "name": "Chikankari" },
    { "name": "Awadhi biryani" }
  ]
}
Path to typeValue you get
titlePocket Guide to Lucknow
user.address.cityLucknow
items.0.nameChikankari
items.1.nameAwadhi biryani

Three rules to remember

  • Go one level at a time and put a dot between the names: user.address.city.
  • For a list, use the item number. Counting starts at 0, so the first item is items.0, the second is items.1.
  • If a name itself contains a dot, write a backslash before that dot: site\.name.

The widgets

After you activate the plugin, Elementor shows a group called APIBridge in its widget panel. Every widget works the same way: choose a connection, then choose the field (path) to show. The display widgets also let you set your own text for while the data loads, for when a value is empty, and for when loading fails.

WidgetUse it to
API TriggerLet visitors type a value or click a button to get data. See below.
API HeadlineShow a single value as a heading. You can add text before and after it, and choose the HTML tag.
API Text / ListShow one value as text, or a whole list. You choose how many items to show and which fields to show for each item.
API ImageShow an image whose address comes from the API. You can set a fallback image, alternative text, and lazy loading.
API ButtonShow a button. The button text and the link can come from the API, or you can type a fixed text or link. It can hide itself when there is no valid link.
API Progress BarShow a number as a bar. You decide which value means 100%.
API Star RatingShow a rating as stars, with the number next to them if you like.
API AlertShow a message box, for example a notice taken from the API.
API Icon BoxShow an icon with a title and text from the API.
API Image BoxShow an image with a title and text from the API.
API TestimonialShow a quote with the name of the person.
API VideoShow a video whose address comes from the API. The player can wait for a click before loading.

With APIBridge Pro you also get Counter, Accordion, Tabs, Table, Card Grid and Timeline. See APIBridge Pro.

API Trigger: let visitors ask for data

Use API Trigger when the visitor decides what to look up, for example "type a city and see its weather". It shows an input field and a button.

  1. Create a connection and choose Input required (see the fields).
  2. Add the API Trigger widget and pick that connection.
  3. Add other APIBridge widgets on the same page and pick the same connection. When the visitor searches, all of them update at once, without reloading the page.

In the widget you can change the label, the placeholder text, the button text and the messages shown while loading, when the input is wrong, and when there are too many requests. There is also a message for screen readers that tells blind visitors when the results are ready.

For a connection that loads on page view, you can switch on Show a button for "load on page view" connections so visitors can refresh the data by hand.

Good to knowTo protect your API quota, visitors have to wait a short time between two searches. You can change this in Settings.

Logs

Open APIBridge → Logs to see requests that went wrong. This is the first place to look when a widget shows nothing.

  • Each entry shows the connection, the time, the status and how long the request took. Open an entry for the error details.
  • Use the search box and the status filter to find entries quickly.
  • Delete all log entries clears the list.

By default only failed requests are logged. API keys, header values and what visitors type are never written to the log.

Settings

Open APIBridge → Settings. The defaults suit most sites.

SettingWhat it does
What to logErrors only (recommended) or Everything. Use Everything to debug, then switch back, because it can grow quickly on busy sites.
Keep entries for (days)Older log entries are deleted automatically once a day. This keeps your database small.
Maximum number of entriesA safety limit. If it is reached, the oldest entries are removed first.
Requests per minute, per visitorHow many requests one visitor may send per minute. Protects you from bots.
Requests per minute, per connectionTotal calls to the API from all visitors together. Cached results do not count.
Wait between submissions (seconds)How long one visitor must wait between two searches or clicks on the same connection.
Anonymous usage dataOff unless you switch it on. Helps the author improve the plugin.
Delete all APIBridge data when the plugin is deletedLeave this off to keep your connections and settings if you reinstall the plugin later.

In the three limit fields, 0 turns that limit off. This is not recommended.

APIBridge Pro Pro

APIBridge Pro is a separate add-on. The free plugin is not a trial and keeps working as long as you like. Pro adds more:

  • Advanced widgets: Counter, Accordion, Tabs, Table, Card Grid and Timeline, built from your API data.
  • Dynamic Tags: use any API field inside Elementor's own widgets, with the same field picker.
  • Error e-mail notifications: get an e-mail when an API request fails.
  • Priority e-mail support, and future Pro features at no extra cost.

Install and activate Pro

  1. Download the APIBridge Pro plugin from your account on lasu.in.
  2. In WordPress go to Plugins → Add New → Upload Plugin, then install and activate it.
  3. Open the License screen under APIBridge and enter your license key.

Pro needs the free APIBridge for Elementor plugin to be installed and active. If it is missing, Pro will not activate and tells you why. For the same reason, the free plugin cannot be deleted while Pro is installed. Delete Pro first.

Dynamic Tags

In any Elementor widget, click the small database icon next to a field (the Dynamic button) and look for the APIBridge tags:

TagUse it for
API TextHeadings, paragraphs, buttons and any other text field.
API NumberAny field that expects a number.
API URLLinks, for example a button link.
API ImageImage fields.

Choose a connection and a field, just as in the APIBridge widgets.

Live updateAPI Text and API Number tags have a switch called Update live from API Trigger, which is on by default. When a visitor uses an API Trigger widget on the same page with the same connection, the tag shows the new data immediately, with no reload. Turn it off if you use the tag inside an HTML attribute, such as image alt text.

Error e-mail notifications

Go to APIBridge → Settings and find Error e-mail notifications.

  1. Switch on Send an e-mail when an API request fails.
  2. Enter the address in Send to.
  3. Choose How often: Right away, or One summary per day (about 8:00, only if something failed).
  4. Click Save, then Send test e-mail.

Each e-mail names the connection, the time, the exact reason and the page where it happened. The same problem on the same connection is e-mailed at most once every 15 minutes, and never more than 20 e-mails per hour. Successful requests never send e-mails.

E-mail not arriving?APIBridge sends e-mails the way your site already sends mail. If the test e-mail shows a note about plain PHP mail, your hosting probably accepts mail but does not deliver it. Install an SMTP plugin such as WP Mail SMTP, connect a real mail account, and send the test again.

Fixing problems

The widget says "please select an API connection"

Open the widget settings and choose a connection in the Connection box. If the list is empty, you have not created a connection yet. Use the Create one link.

The widget says "please enter the JSON field path"

Pick a field with Pick from live data, or paste a path you copied with Copy path on the Test Connection screen.

Test Connection works, but my widget shows nothing

The path is probably not exact. Check capital letters, check that you used the item number for lists (items.0.name), and copy the path again with Copy path. Also check that the widget uses the same connection you tested.

The data on my page looks old

The connection is probably caching results. Edit the connection and set Remember successful results for to a shorter time, or to Do not cache.

I see "Too many requests"

A visitor sent requests too fast, or the limits in Settings are set very low. Raise the limits a little, or increase Wait between submissions only if you see abuse.

The connection form says my saved header values can no longer be read

This happens when your site's security keys (in wp-config.php) change, for example after a migration. Enter the header values again and save.

The test works but the API says my key is wrong

Check the header name and the value spelling. Many APIs want the value as Bearer your-token, others want only the key. Your API documentation shows the exact form.

I do not get error e-mails

First, check that the license is active and the switch is on. Then click Send test e-mail. If you see a note about plain PHP mail, or no e-mail arrives, install an SMTP plugin such as WP Mail SMTP. Also look in the spam folder.

Where can I see what went wrong?

Open APIBridge → Logs and open the entry for the failed request. It shows a clear reason. To record successful requests too, switch What to log to Everything for a while.

Security and privacy

  • Requests come from your server. Visitors never see your API address, headers or keys.
  • Keys are encrypted when saved, and are never displayed again.
  • Input is checked. What a visitor types is validated against the value type you chose before anything is sent.
  • Limits protect you. Per-visitor and per-connection limits stop bots and accidental floods.
  • Logs stay clean. Keys, header values and visitor input are never written to the log.
  • Nothing is sent to the author unless you agree. Anonymous usage data is off until you switch it on.
