Outbound Campaign API 422 Validation Error on Custom Disposition Mapping

Trying to understand the specific validation constraints applied to custom disposition mappings when provisioning outbound campaigns via the Platform API.

Our AppFoundry integration handles campaign setup for enterprise clients, and we are encountering a 422 Unprocessable Entity response when attempting to link custom disposition codes to the dialout:campaign:admin scope. The error payload indicates that the dispositionCode field contains an invalid reference, yet the same UUIDs work perfectly when applied manually through the Genesys Cloud UI.

Here are the technical details:

  • Endpoint: POST /v2/dialout/campaigns
  • SDK: Genesys Cloud Python SDK v19.0.0
  • Environment: Production (US-PROD)
  • Error Snippet: {"code": 422, "message": "Disposition code mapping is invalid.", "errors": ["The specified disposition code does not exist or is not enabled for this organization."]}

We have verified that the disposition codes are active and belong to the correct campaign group. The issue appears to be isolated to the API call sequence. Our current flow creates the disposition codes first, waits for a 200 OK, and then immediately triggers the campaign creation with the mapping. We suspect there might be a propagation delay or a specific dependency between the dialout:disposition and dialout:campaign scopes that is not documented in the standard API references.

Is there a required delay or a specific endpoint we should poll to confirm disposition code availability before referencing them in the campaign body? Additionally, are there known issues with multi-org OAuth tokens where the disposition code context might be incorrectly resolved if the service account has access to multiple organizations but the campaign is being created in a secondary org?

Any insights into the internal validation logic or best practices for sequencing these API calls would be appreciated. We are trying to minimize manual intervention in our deployment pipeline.

I normally fix this by ensuring the dispositionCode matches an existing definition in the global settings. The API rejects mappings to undefined codes. Verify the code and description fields align with the /api/v2/outbound/dispositions list. Also, check that the type is set correctly for the campaign’s routing strategy.
