We are looking for an API to send and receive messages (incl. multimedia) on whats app programmatically and reliable with client sim card provided by us. Furthermore original client app features are gladly appreciated.
The API should handle a lot of communication traffic seamlessly (it will be used on a 3000+ community member club) and may be programmed in all common languages and services supported by linux servers.
A good reference work can be found on [url removed, login to view] Unfortunally this API is no longer supported and quiet buggy on multimedia messaging and has issues with the new end-to-end encryption.
For proof of concept an API documentation and API access is needed before first milestone. Complete API sourcecode w/ instructions need to be supplied before final payment.
