Can't connect FreePBX Rest Interface (FreePBX business app)

Question

I’ve deployed FreePBX business app to DO droplet server.As I was following this guide (https://sangomakb.atlassian.net/wiki/spaces/PG/pages/25690223/REST+API ) I could not get new access token. It gives me an eror “invalid client”.Here is my configuration in Postman.image alt textI could not fill the available token input (bearer token). I am not sure where I can get it. New token configuration has same data with one in my FreePBX web admin panel. Please let me know what I’ve missed.

Hi there! This error typically points to an issue with the OAuth client credentials or the configuration in Postman. Here are a few things that I would recommend checking: 1. Verify OAuth Client Credentials Ensure that the OAuth client credentials used in Postman match exactly with those configured in FreePBX. These credentials are usually set up in the FreePBX administration interface. Log in to your FreePBX admin panel. Navigate to the section where OAuth clients are managed. This might be under “Admin” or “Applications,” depending on your FreePBX version. Check the client ID and secret; make sure they are exactly the same in your Postman configuration. 2. Correct Postman Configuration In Postman, setting up the request for an access token should be done carefully: Set the request type to POST. The URL should be the token endpoint of your FreePBX API (usually something like http(s)://<your-freepbx-server>/admin/api/api/token). In the Body of the request, select x-www-form-urlencoded. Add the following key-value pairs: grant_type: should be set to client_credentials. client_id: your OAuth client ID. client_secret: your OAuth client secret. 3. Check Redirect URI Make sure that the redirect URI in your OAuth client configuration in FreePBX matches with any URI you’re using in Postman. Sometimes, even if not used, a mismatch can cause issues. 4. FreePBX Configuration Ensure that your FreePBX instance is properly configured to handle REST API requests: Check that the REST API module is installed and enabled. Ensure that the network configuration allows API access (check firewalls or network settings). 5. Server Response Carefully examine the response you’re getting from the server: Look for any additional error messages or codes in the response. Check server logs if possible for more detailed error messages. Also, make sure that there are no network issues or firewalls blocking your request from Postman to your FreePBX server. On another note, sometimes, simply refreshing the settings or restarting the FreePBX server can resolve unexpected glitches. Best, Bobby
