Connect Spotler Mail+ to Hypamoon
Yes, with one catch. Spotler Mail+ has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today.
OpenThe check
Three questions about the API of Spotler Mail+, answered from its own docs.
- Public API docs
- Yes. Interactive reference for contacts, mailings, forms, campaigns, orders and products, linked from spotler.com/integrations/api. Read the docs
- A key you create yourself
- Yes. The consumer key and secret for OAuth 1.0a are created in your own Spotler Mail+ account. restdoc.mailplus.nl
- Versions or a changelog
- Yes. The spec carries apiVersion 1.0.0 and the base URL restapi.mailplus.nl/integrationservice has stayed the same for years; there is no public changelog. restdoc.mailplus.nl
- How it signs in
- OAuth 1.0a one-legged, with a consumer key and secret you create in your Spotler Mail+ account.
- Webhooks
- Not confirmed.
- Hosting
- Cloud
What you can build
Add contacts from your web forms and orders to Spotler Mail+, and pull mailing results into your own dashboard.
Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. How adapters work
Good to know
- Spotler Mail+ signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Spotler Mail+ takes more work: ask your chat to check this first.
- The REST API covers contacts, mailings, campaigns, forms, audiences and more, in JSON or XML. Requests are signed with OAuth 1.0a.

Tool not listed? Ask the chat to check its API.
The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.
Check if [software] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
Fill in the name of your software. Checking needs no connection to Hypamoon.
