Thredd (formerly Global Processing Services / GPS) is a London-headquartered issuer-processor and next-generation payments technology company, founded in 2007, rebranded to Thredd in 2023, and backed by Advent International. It provides card issuing and issuer processing for fintechs, neobanks, banking-as-a-service platforms, and program managers across Mastercard, Visa, and Discover, spanning 40+ countries, with real-time transaction authorization (External Host Interface / EHI), digital-wallet tokenization (Apple Pay, Google Pay), 3-D Secure / strong customer authentication, card controls, and fraud / scam detection. Its home market is the United Kingdom. Thredd ships a genuine public developer surface: a self-serve Developer Portal (devportal.thredd.com) that grants a sandbox client id and secret, an API Hub REST API at api.thredd.com, and a ReadMe-hosted API reference (cardsapidocs.thredd.com) documenting roughly 129 endpoints across more than a dozen product OpenAPI definitions (core cards, transactions, credit, custom PAN, card limits, card controls, digital wallets, 3DS, ACH, open banking, alias directory, and web services). Authentication is FAPI-grade OAuth2 client-credentials using private_key_jwt client assertions over mutual TLS, brokered by Cloudentity with Raidiam Connect acting as the certificate authority; webhooks and event subscriptions are supported. The underlying OpenAPI files render only through the hub and are not anonymously downloadable.
Thredd publishes 10 APIs on the APIs.io network. Tagged areas include Payments, United Kingdom, Issuer Processor, Card Issuing, and Payment Processing.
The Thredd catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Thredd’s developer surface includes authentication, changelog, sandbox, documentation, API reference, getting-started guide, signup flow, and 16 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.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
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/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/thredd: open an issue to ask a question, or submit a pull request to add artifacts.
