I have to send messages to the customer's whatsapp number programatically.
What are the pre requirements/needs?
Do I need to convert/register my personal number to business account?
Is there any API provided by whatsapp for this?
I wanted to know how I can send text to a specific whatsapp contact. I found some code to view a specific contact, but not to send data.
Cursor c = getContentResolver().query(ContactsContract.Data.CONTENT_URI, new String[] { ContactsContract.Contacts.Data._ID }, ContactsContract.Data.DATA1 + "=?", new String[] { id }, null); c.moveToFirst(); Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("content://com.android.contacts/data/" + c.getString(0))); startActivity(i); c.close(); This works fine for viewing a whatsapp-contact, but how can I add some text now? Or didn't the Whatsapp-developer implement such kind of an api?
