User-Agent

Identify your integration on every request with a name and a valid contact email:

User-Agent: Integration Name <contact@company.com>

Example with cURL:

curl -i \
  -H "Authorization: Bearer $DUNNING_TOKEN" \
  -H 'Content-Type: application/json' \
  -H 'User-Agent: My Integration <dev@mycompany.com>' \
  -X GET 'https://api.dunning.kobana.com.br/api/v1/charges'

The value goes into the audit trail and is used by support to locate your calls — and by our team to warn you before blocking if the integration misbehaves. Unidentified requests make troubleshooting harder: treat the header as required.
