# 61007: Add-ons: Response body too large

Log Level: ERROR

## Description

This error occurs when a Marketplace Add-on Listing returns a synchronous result payload larger than 64 KB. Twilio removes the oversized payload and returns this error instead.

### Possible causes

* The Add-on provider returned a response payload that exceeded the 64 KB limit for synchronous Marketplace results.
* You are using the listing in a synchronous integration point, such as Lookup, incoming SMS, or incoming Voice, where Twilio returns results immediately and enforces the 64 KB size limit.
* Your listing configuration may be returning more detail than fits within the synchronous result limit.

### Possible solutions

* Reduce the size of the synchronous result so it stays under 64 KB. If you manage the listing, return a smaller result object and remove optional fields that are not required.
* Review the listing configuration in Console and adjust any listing-specific configuration parameters so the provider returns only the data you need.
* If you need larger result payloads for recording analysis, use an asynchronous Add-on Listing instead. Asynchronous results support payloads up to 100 MB and can be retrieved through the Add-on Results API.
* Check the Add-on result in the response path for your integration. Lookup returns results in `add_ons`. Incoming SMS and incoming Voice callbacks return results in `AddOns`.
