looks like you're sending the headers inside the body, that's why you're getting this error.
please update your request and try again, it should be something like this

curl -X POST \ https://api.textbee.dev/api/v1/gateway/devices/${DEVICE_ID}/sendSMS \ -H 'x-api-key: ${API_KEY}' \ -H 'Content-Type: application/json' \ -d '{ "recipients": ["+123556789"], "message": "Hello World!" }'
