20413: Request Entity Too Large

Twilio returned this error because the HTTP request body is larger than the maximum size the endpoint accepts. Reduce the size of the payload and send the request again.

• The request body includes too much data for the resource you are creating or updating.
• You are sending a large media file, document, or encoded payload in the request body instead of using a supported media URL or upload flow.
• Your application is sending an unexpectedly large JSON, XML, or form-encoded request because of duplicated fields or oversized parameter values.
• A webhook or integration is forwarding a request to Twilio without enforcing payload size limits.

• Reduce the size of the request body before sending the request.
• Remove unnecessary parameters, repeated fields, or extra metadata from the payload.
• If you are sending media, use the product's supported media handling method instead of embedding large binary content directly in the request.
• Check your application logs to confirm the final serialized request size your client sends to Twilio.
• Review the API resource you are calling and make sure you are only sending parameters that the endpoint supports.
