In step 2, Connect your apps, you choose the two applications you want to link and make sure APIcenter can connect to both.
What you see
- Two blocks, Application 1 and Application 2, with an arrow between them.
- When you click an empty block, a panel opens with:
- Your applications: applications you connected before. You can reuse them straight away, without logging in again.
- Connect a new application: all applications you can connect, with a Search field.
- A filled block shows the logo and name of the application, a pencil to edit the connection and a bin to remove the application from the block.
Connect an application
- Click Application 1.
- Click an application under Your applications, or search for it under Connect a new application and click it.
- For a new application, fill in the Display title (the name you see in APIcenter) and the connection details the application asks for.
- Click Save.
- If an Authorize button appears, click it and log in to the application in the window that opens.
- Click Test Connection. When the test succeeds, the application appears in the block.
- Do the same for Application 2.
- Click Next. APIcenter creates the integration and opens Step 3: Choose your flows.
Next to the form you may see a video, information about the API of the application and the link Where can I find my API details? to its manual.
Tips
- For the second application, the list only shows applications that can be paired with the first one. If yours is missing, that combination is not available.
- If the test fails, you see Test Connection Error with the message of the application. Check the details, click Save and test again.
- The bin only removes the application from this block. The application stays in your account.
- You manage your connected applications on the Applications page. See also New application, and for AFAS AFAS.
