How to create API requests?

You can find all the SendFox API Endpoints here -

This is an example of how to create an API request using Postman app.

1. Create the Request in Postman:

  • Click on "New", add the request name and collection, and click Save.

  • Log in to your SendFox account and go to your Account Settings --> API
  • Click on Create New Token and add a name
  • This will give you a Personal Access token so copy it from there as this is the only time you will be able to see it.

  • Go back to Postman and click on Authorization tab
  • From the dropdown menu select OAuth 2.0
  • Paste the Access token you generated from SendFox

  • If everything was done correctly, you should see the green dot on the Authorization tab.

3. Write the request

Now you can create GET/POST requests as you like, here's an example of how to create a request which will add the email address and first name to a specific list in SendFox.

For this specific example, we will need to create POST request with additional parameters that will add first name and push the contact to a specific list.

  • Add the email as a "Key" and enter the email address as a "Value"

  • Do the same for "first_name"

  • Now you need to specify a list, and to do that, first go to your SendFox account in Lists tab
  • Click on the list you want, and copy the List ID from the URL like this:

  • Each list has it's own unique value, so just make sure you're using the correct one
  • When you have the List ID, head back to Postman and create another parameter like this

  • Just keep in mind that your list will have a different value, so you will need to add your own there.
  • Lastly, add this header to the "Headers" tab to ensure responses are useful. This way if there's an error, it will be clearly noted in the response:

4. Test the request

After you've done all this, click on Send to test the request and you should see the response like this:

And if everything was set up correctly, you should see that email in your SendFox list:
