The Messaging API v2.1 allows you to send and receive SMS (text messages) and MMS (multimedia messages) on long code and toll-free numbers. This version supports compact and JSON API formats. All of your Flowroute phone numbers are MMS-enabled. MMS total size limit is currently 750kB.
Messages v2.1 supports HTTP Basic Auth. Use your API credentials from Flowroute Manage to authenticate: Access Key serves as your username while Secret Key serves as your password.
Messages v2.1 is versioned according to Flowroute's philosophy on resource-level breaking changes.
While both the destination mobile operator and device ultimately determine compatibility, most mobile operators and handsets render the MMS file types specified below:
|JPEG||3GP (also P2 and Timed Text)||AMR (also AMR-NB)||Plain|
|H.261||MP3 (MPEGs are converted to this format)||RTF|
|H.263 (also 1998 and 2000)||Basic||Calendar|
|Microsoft's Advanced Systems Format (x-ms-wma)||Vorbis|
|3GPP (also 3GPP2)|
