• A custom message processor in Amazon Connect is activated either with the 'Set recording, analytics and processing behavior' flow block, using the action 'Set message processor' with channel 'Chat', or by calling the StartContactMediaProcessing API. in context
• The StartContactMediaProcessing and StopContactMediaProcessing APIs apply only to custom message processors; built-in redaction is configured exclusively through the flow block. in context
• A copy of each chat message is sent to the custom processor Lambda, and if a valid response is received within the timeout, the content of that response becomes the new canonical form of the message. in context
• When message processing is enabled in Amazon Connect, every plaintext, markdown and JSON chat message passes through the configured processor before delivery to participants. in context
• The input event delivered to the Amazon Connect custom processor Lambda carries a chatContent object with content, contentType, participantId, displayName, participantRole, contactId and initialContactId; the documented event format has no language field. in context
• If message processing fails in Amazon Connect, the administrator's configuration decides whether the original unprocessed message is delivered or suppressed. in context
• Amazon Connect message processing is not available in the AWS GovCloud (US-West) Region. in context
• Amazon Connect message processing intercepts and modifies chat messages before they reach any participant. in context
• Amazon Connect honors the custom processor Lambda function's configured timeout, which must be between 3 seconds and 3 minutes. in context
• Because the documented processor event carries participant role but no language, a translation Lambda on Amazon Connect has to determine source and target languages itself, for example by language detection or by its own lookup of contact data. inferred in context
• Amazon Connect message processing stays active for the entire duration of the chat, including across a transfer when an individual contact segment ends, and it does not retroactively process messages sent before it was enabled. in context
• When built-in redaction and a custom message processor are both enabled in Amazon Connect, the output of redaction becomes the input for the custom processor. in context
• Before a custom processor Lambda can be used, it must be added to the Amazon Connect instance with the use case 'Custom processor lambda', or associated through CreateIntegrationAssociation with IntegrationType MESSAGE_PROCESSOR. in context
• The processed content returned by the custom processor Lambda replaces the original message when it is published to chat participants. in context
• The Amazon Connect custom processor Lambda must return a status of PROCESSED, APPROVED or REJECTED, with processed content of type text/plain, text/markdown or application/json. in context
• With Amazon Connect message processing, processed chat messages replace the originals in the S3 chat transcripts folder, and the unprocessed original transcript is stored in a separate S3 folder whose path prefix begins with 'Unprocessed'. in context
• AWS documentation names language translation through third-party services as a use case for a custom message processor Lambda in Amazon Connect chat; translation is not offered as a built-in processing option alongside built-in sensitive data redaction. in context
