How it works

Programmatic group operations

Use FlareSend to create groups, manage participants where supported, and broadcast updates without manual phone taps.

Send messages into WhatsApp groups via API
Automate course, church, or team announcements
Combine with scheduling for recurring updates
Useful for schools, SACCOs, and community orgs
Developer-friendly REST endpoints

How FlareSend connects: You link your own WhatsApp number by scanning a QR code, then call a simple REST API. Setup is fast and does not require Meta Cloud API business verification. For very large official-template campaigns, Meta’s Cloud API may still be a better fit — see the comparison.

Group message example

curl -X POST https://api.flaresend.com/send-message \

  -H "Content-Type: application/json" \
  -d '{
    "recipients": ["1203630xxxxx@g.us"],
    "type": "text",
    "text": "Reminder: class starts at 6pm EAT."
  }'

FAQ

Quick answers

Can I message groups I do not own?

You can only act within WhatsApp permissions for the linked account. Prefer groups you administer.

Is this for spam?

No. Unsolicited group spam risks bans. Use FlareSend for consented community operations.

Do you support channels too?

FlareSend also supports WhatsApp Channels workflows depending on your plan features.
