1. Create a token or sandbox company
In Fintoro, open the integrations area for Fintoro API. This is where you manage tokens and sandbox companies.- In the production company, create tokens for real integration traffic.
- Under the production company, create multiple sandbox companies for isolated testing.
- Each company has its own tokens.
https://app.fintoro.sk/api/public/v1, but with a sandbox company token.
2. Make your first request
For the first verification, use a simple read-only lookup endpoint:200 OK and a list of countries in data.
If the request returns 200 OK, you have validated the host and token.
3. Prepare for write operations
- Create a token with the lowest scope that still fits the use case.
- Load the lookups and reference tables required for your payloads.
- Verify read scenarios in the production or sandbox company.
- If you need to react to changes continuously, implement Webhooks. Use polling at most for the initial import or reconciliation checks.
- Before the first write flow, review API conventions and Errors, rate limits, and retries.
4. Review the basic decisions
- whether the integration belongs in the production company or a sandbox company,
- how you want to name tokens by system or partner,
- if you will consume webhooks, prepare the receiver endpoint, deduplication, and secret storage,
- which lookups you want to preload into cache or a local reference table,
- which tags in the API reference matter for your first write flow.
