token used to call REST linked service
Hello stephanep
You are correct in Fabric pipelines, when using a REST-linked service with OAuth 2.0 Client Credentials, the token is generated once at the start of the dataflow execution and reused for subsequent calls. This can lead to 401 errors if the token expires mid-execution.• Access tokens typically expire in 5–10 minutes, while refresh tokens may last up to 30 days.
• Fabric/ADF does not automatically refresh tokens during a dataflow execution. If the pipeline exceeds the token’s lifespan, subsequent calls fail with a 401 error.Some workarounds
Use a Web Activity to fetch a new access token before each API call or series of requests
GET https://<token-endpoint>
Headers: Authorization: Basic <base64(client_id:client_secret)>
Body: grant_type=client_credentialsImplement retry logic to detect 401 errors and trigger token refresh
