80102: Participant Already In Interaction

This warning appears when you try to add a participant to an interaction and that participant has already been added. For SMS and WhatsApp participants, the address and proxy_address binding can exist in only one non-closed conversation, so trying to add the same participant to another interaction can fail.

• The participant is already part of the interaction.
• For SMS or WhatsApp, the same address and proxy_address pair is already bound to another non-closed conversation in the active or inactive state.
• You created an outbound interaction for a customer who already has an ongoing conversation, so the participant was not added to the new interaction.

• Check whether the participant is already in a non-closed conversation before you create the interaction. Use the Participant Conversation Resource to look up existing conversations for that participant.
• If the participant is already in an existing conversation, continue that conversation instead of creating a new interaction for the same binding.
• Create the conversation first and then create the interaction. If the participant add fails, the response returns the conversation SID for the conversation that already contains that participant.
