MMS – Max Files, Max File Size, Gateway Timeout, etc


A couple of MMS (i.e. POST "/messages/mms") questions requiring clarification please…

• Is there a maximum number of file attachments per MMS (i.e. "MMSContent" array)?
• Is there a maximum individual file size per MMS (i.e. each "MMSContent" array item)?
• Is there a maximum total file size per MMS (i.e. all "MMSContent" array items)?
• Is there a script timeout on the POST "/messages/mms" endpoint?

For context, I'm currently unable to send large-ish GIFs (e.g. 2.3MB) via the MMS Messaging API.

When I try to do so, I'm hit with 504 responses, for example…


HTTP/1.0 504 Gateway Timeout
Cache-Control: no-cache, private
Connection: keep-alive
Content-Length: 222
Content-Type: application/json
Date: Tue, 31 Oct 2017 02:53:15 GMT
Server: Apigee Router

"message":"Technical error : Gateway Timeout : An error has occurred while processing your request, please refer to API Docs for summary on the issue"


As a paying customer, I'd appreciate your help sorting this out as soon as possible.
