Tab

Tab (tab.travel) is a London-based payment platform built specifically for independent tourism and hospitality businesses — hotels, hostels, tour operators, retreat centers and activity providers. It lets these merchants take card payments wherever their guests are, from in-advance deposits and online booking pages to in-person, on-the-move transactions via a mobile app, and to plug into an existing booking engine, PMS or OTA ecosystem. Tab natively handles 140+ currencies, pays out weekly in the merchant's local currency, and advertises transparent pricing from 2.9% per transaction with no hidden fees. Founded in 2015 by Mark Datta and backed by Y Combinator (W2015), Tab also operates a consumer-facing social-commerce guide for discovering and booking travel. This profile is maintained by the API Evangelist network; Tab does not currently publish a public developer API, SDKs or API documentation.

Tab is profiled on the APIs.io network. Tagged areas include Company, Payments, Travel, Tourism, and Hospitality.

Tab’s developer surface includes pricing, signup flow, engineering blog, and 4 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/tab: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
