Wapito

Create a label

POSThttps://api.wapito.com/v1/labels

Send a channel token on every request: Authorization: Bearer wpt_YOUR_TOKEN

Creates a new label with a name and one of the twenty WhatsApp colour slots. WhatsApp caps the number of labels per Business account, so reuse labels rather than minting one per campaign. The created label is immediately available on the linked phone as well, which keeps human operators and automations working from the same taxonomy.
