Salt Edge Account Information

5,000-plus banks in more than 50 countries, by Salt Edge's own count. Rate limit exceeded returns HTTP 406 RateLimitExceeded, not 429.

TrueLayer

FCA and Central Bank of Ireland authorised, holding the AISP and PISP licences itself. No public pricing anywhere on the site or in the docs.

Salt Edge Account Information

1. Treat HTTP 406 with error_class RateLimitExceeded as a rate limit and back off; it isn't a content-negotiation error
2. Start with fakebank_simple_xf in country XF; it needs no bank sandbox
3. Sign requests from the start even in Test, so the move to Live doesn't change your client
4. Follow next_page from the meta block rather than building from_id URLs yourself
5. Revoke with PUT /api/v6/consents/{consent_id}/revoke when the user is done

TrueLayer

1. Use auth.truelayer-sandbox.com and api.truelayer-sandbox.com with a separate sandbox client; live credentials don't work there
2. Send the user's IP when they're present, or a bank allows 4 calls a day per account
3. Check the retry column of the Data API error table before retrying; codes marked No need the user or a config fix
4. Set data_access_type to one_time for a single read and skip the 90-day reauthorisation
5. Append .md to any docs URL to get the page as Markdown
