API Authentication Issues

Problem

An external system cannot connect to Yanet Barcode API.

Check 1 — Check API Access

Go to:
Settings → API Access
Make sure API Access is available for your plan and that credentials have been generated.

Check 2 — Check Client ID

Compare the Client ID in Yanet with the Client ID configured in your external system.
Make sure there are no extra spaces or missing characters.

Check 3 — Check Client Secret

Check that the Client Secret in the external system matches the current credential.

Important: Never paste your Client Secret into a public support request.

Check 4 — Check whether the key was regenerated

If you clicked Generate New Key, the previous credentials may no longer be the credentials your integration should use.
Update the external system with the current credentials.

Step 5 — Test authentication

Run the connection or API request again.

Result

The external system should authenticate successfully when the correct credentials and API configuration are used.

Note: For API-specific request formats, headers, and endpoints, refer to the Barcode Print API Documentation.
