Details
These APIs were originally introduced to support blind and consult transfers to external contacts. However, due to edge cases where the implementation cannot reliably ensure that the transfer destination is a valid external contact, they are being deprecated.
Customers should migrate to the following replacement APIs, which enforce proper external contact handling and address the limitations of the previous implementation:
• POST /api/v2/conversations/{conversationId}/participants/{participantId}/replace/contact/external
• POST /api/v2/conversations/calls/{conversationId}/participants/{participantId}/consult/contact/external
Customer Impact
• Genesys Cloud UI, CRM integrations, and other Genesys Cloud products have already migrated to the new endpoints.
• Customers using the deprecated APIs must update their integrations to use the replacement endpoints prior to removal.
• The deprecated permissions will be removed following their deprecation phase.
Impacted Resources
• POST /api/v2/conversations/{conversationId}/participants/{participantId}/replace/external
• POST /api/v2/conversations/calls/{conversationId}/participants/{participantId}/consult/external
