Authentication

All requests to the Kler API (except the Providus webhook endpoint) must include your organisation’s API key in the request headers.

x-api-key: YOUR_API_KEY

Example

curl https://api.kler.africa/v1/sessions \
  -H "x-api-key: YOUR_API_KEY"

API keys are provisioned per organisation. Contact hello@kler.africa to get yours during the early access period.

Never expose your API key in client-side code or public repositories.
Rotate your key immediately if you believe it has been compromised.
The Providus webhook endpoint (POST /v1/webhooks/providus) does not use API key auth — it uses HMAC signature verification instead.
