Yes, you can definitely send a broadcast message using the WhatsApp API. There are a few restrictions on the type of messages you can send.
- The message that you need to send must be in the format of a message template.
- Message templates need to be pre approved by Meta
- Each template belongs to one category: Marketing, Utility or Authentication. You can send promotional broadcasts with an approved Marketing template. Send only to customers who agreed to receive messages from you (opt-in).
After you have an approved WhatsApp message template, you can send it from DelightChat. Go to WhatsApp Marketing > Broadcasts and click Create New Broadcast, then choose Regular Broadcast. Enter a Campaign Name. For the audience, either select a customer segment or upload a CSV of customer phone numbers (start the CSV with country code, then phone number). Select your message template and fill in its variables. Under Message Scheduling, choose Immediately or Custom Date & Time (at least 15 minutes from now). Then click Publish Broadcast, or click Save as Draft to finish later.
We have written a guide to sending promotional broadcasts via WhatsApp using DelightChat. DelightChat does not send a broadcast to customers who opted out (see WhatsApp Marketing > Opt-Outs). Some customers may not get your message because Meta limits how many marketing messages one person can receive (error code 131049). To try these numbers again, turn on Enable Retry Broadcast when you set up the broadcast. You can schedule up to 3 retries, 1 to 6 days after the original send.
