SDKs
Language libraries for the Bytloop Mail API. Officially supported and community.
The Bytloop API is intentionally close to HTTP so any language with a half-decent HTTP client can talk to it in a few lines. Official SDKs are on the roadmap; until they ship, the REST API is the canonical interface.
In the meantime#
The REST API is designed to feel obvious from any HTTP client. Every guide in these docs includes a curl example, and most include Node and Python snippets. Start with:
- Send a transactional email — the primary sending endpoint with curl, Node, and Python.
- Webhooks — receiving events with a signed HMAC handler.
- API explorer — an interactive reference that fires requests against your workspace with a click.
Community SDKs#
None yet. If you build one, open a pull request against the docs and we will link it here once we have taken a look.
What the SDKs will do#
When they ship, the official SDKs will:
- Sign requests with your API key and add the required headers.
- Type every request and response so autocomplete works everywhere.
- Handle retries with exponential backoff on
429and5xx, including honouringRetry-After. - Provide a helper for verifying webhook signatures (see the hand-rolled Node example on the Webhooks page).
Nothing in the SDKs will do anything the REST API cannot — they are a convenience layer, not a replacement.
