This GitHub Action will handle authenticated API requests for you, allowing you to save the data from the request into your workspace as an environment variable and a file. Using this action will allow you to save data from these queries on a schedule so they can be used in a static page without exposing your API credentials. You can read more about the inspiration for this action here.
Maintenance of this project is made possible by all the contributors and sponsors. If you'd like to sponsor this project and have your avatar or company logo appear below click here. 💖
You can include the action in your workflow to trigger on any event that GitHub actions supports. You'll need to provide the action with the endpoint you'd like to request along with any configuration options as stringified JSON.

uses: JamesIves/fetch-api-data-action@v2
with:
endpoint: https://example.com
configuration: '{ "method": "GET", "headers": {"Authorization": "Bearer ${{ secrets.API_TOKEN }}"} }'Once the action has run the requested data will be exported into the fetch-api-data environment variable and will also be available as a .json file in your workspace located by default in the fetch-api-data-action/data.json directory. If you need something other than .json file please refer to the format parameter.
You can combine the use of this with the GitHub Pages Deploy Action to trigger scheduled updates to a feed on your website.
You can view a full example of this here.
In one workflow you can fetch data from an API on a schedule and push it to your main branch.

If you'd like to use the functionality provided by this action in your own action you can either create a composite action, or you can install it using yarn or npm by running the following commands. It's available on both the npm and GitHub registry.
yarn add @jamesives/fetch-api-data-action
It can then be imported into your project like so.
import run, {
retrieveData,
generateExport,
ActionInterface
} from '@jamesives/fetch-api-data-action'Calling the functions directly will require you to pass in an object containing the variables found in the configuration section.
import run from '@jamesives/fetch-api-data-action'
run({
endpoint: 'https://example.com',
configuration: JSON.stringify({
method: 'GET',
headers: {Authorization: `Bearer ${process.env['TOKEN']}`}
})
})The with portion of the workflow must be configured before the action will work. You can add these in the with section found in the examples above. Any secrets must be referenced using the bracket syntax and stored in the GitHub repositories Settings/Secrets menu. You can learn more about setting environment variables with GitHub actions here.
The following configuration options should be set.
| Key | Value Information | Type | Required |
|---|---|---|---|
endpoint |
The URL of the endpoint you'd like to retrieve data from. For example: https://example.com/data. If no configuration is provided then the default request method will be GET. |
with |
Yes |
configuration |
Any applicable configuration settings that should be set such as authentication tokens. You can reference secrets using the ${{ secrets.secret_name }} syntax, or you can reference data returned from the token-endpoint request using the triple bracket syntax: {{{ data.access_token }}}. For more information refer to the Token Request part of the readme and the Fetch API documentation. |
secrets / with |
No |
| Key | Value Information | Type | Required |
|---|---|---|---|
token-endpoint |
If the endpoint API requires you to make a request to get an access token prior to fetching data you can perform this task by specifying a token endpoint. Any data returned from the token end can be referenced in the configuration variable using the triple bracket syntax: {{{ access_token }}}. For more information refer to the Token Request part of the readme; |
with |
No |
token-configuration |
Any applicable configuration settings that should be set such as authentication tokens. You can reference secrets using the ${{ secrets.secret_name }} syntax. For more information refer to the Fetch API documentation. |
secrets / with |
No |
retry |
If you're working with an intermittent API you can toggle this option to true. Doing so will make the action try the request 3 times at random intervals before failing. |
with |
No |
save-location |
By default the save location of the file is fetch-api-data-action/data.json, if you'd like to override the directory you can do so by specifying a new one with this variable. |
with |
No |
save-name |
You can override the name of the exported .json file by specifying a new one here. You should not include the file extension in your name. |
||
variable-name |
Adjusts the name of the environment variable the action generates so long as set-output is true. Defaults to fetchApiData. |
with |
No |
set-output |
Determines if the returned data should be saved as an environment variable or not. This field defaults to true, but depending on your API response length you may need to toggle this. If true, an environment variable and action step output named fetchApiData will be created. |
with |
No |
format |
Allows you to modify the extension of the file saved from the API response, for example you can set this field to json or txt. This field defaults to json. |
with |
No |
encoding |
Allows you to modify the encoding of the file saved from the API response, for example you can set this field to utf8 or hex. This field defaults to utf8. Choose from ascii, utf8, utf-8, utf16le, ucs2, ucs-2, base64, latin1, binary or hex. |
with |
No |
debug |
If set to true the action will log the API responses it receives in the terminal. |
with |
No |
If you need to make a request to another endpoint in order to request an access token or something similar you can do so using the token-endpoint and token-configuration parameters. You can then use the returned token in your configuration variable using the triple syntax like so {{{ tokens.access_token }}}. You can find an example of this below.

# The token endpoint is requested first. This retrieves the access token for the other endpoint.
token-endpoint: https://example.com/auth/token
# The configuration contains secrets held in the Settings/Secrets menu of the repository.
token-configuration: '{ "method": "POST", "body": {"client_id": "${{ secrets.client_id }}", "client_secret": "${{ secrets.client_secret }}"} }'
# Once the token endpoint has fetched then this endpoint is requested.
endpoint: https://example.com/data
# The bearer token here is returned from the TOKEN_ENDPOINT call. The returned data looks like so: {data: {access_token: '123'}}, meaning it can be accessed using the triple bracket syntax.
