21627: Max Price must be a valid float

This error code is obsolete. Historically, Twilio returned 21627 when your request included the maxPrice parameter with a value that was not a valid positive floating-point number. The Message resource marks maxPrice as obsolete, and as of June 3, 2024, the parameter no longer has any effect on message sending. Remove maxPrice from new requests.

• A historical API request included maxPrice with a value of 0.
• A historical API request included maxPrice with a negative value.
• A historical API request included maxPrice with a value that was not a float.
• Your application still sends the obsolete maxPrice parameter in Message resource requests. This parameter is obsolete and no longer has any effect as of June 3, 2024.

• Remove the maxPrice parameter from your Message resource requests.
• If you are troubleshooting an older implementation, set maxPrice to a valid positive floating-point value.
• Review your SMS Geo Permissions settings and allow only the countries where you intend to send messages. Twilio recommends this as a more robust way to avoid unexpected messaging costs.
