90036: Broadcast recipient's 'body' is too long

You receive this error when a broadcast request includes a recipient object whose body value is longer than the allowed limit. For Messaging API requests, Body can be up to 1,600 characters. SMS content that includes non-GSM-7 characters, such as emoji or smart quotes, can also increase message size and affect how the message is segmented.

• One or more recipient objects include a body value that exceeds the allowed character limit.
• Personalized or templated content expands the final body beyond the supported limit for a recipient.
• The message includes Unicode characters that require UCS-2 encoding, which reduces the number of characters available in each SMS segment.
• The broadcast payload was generated without validating the final rendered message length for each recipient.

• Shorten the body value in each recipient object before you send the broadcast.
• Keep the final message body at 1,600 characters or fewer.
• If you personalize content per recipient, render and validate each recipient's final body before submitting the request.
• Remove unnecessary text, links, or repeated content that increases the message length.
• If you are sending SMS, avoid unnecessary Unicode characters when possible and keep messages closer to 320 characters for better deliverability and readability.
