Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.thewalletcrew.io/connectors/overview.md). # Overview Connectors are integration accelerators that help connect The Wallet Crew with existing customer systems — CRM, POS, marketing automation, ticketing, e-commerce, and hardware. They are not plug-and-play solutions. Each customer has specific data models, business rules, and operational processes that shape how the integration is designed and deployed. A connector can include built-in sync logic, configuration tooling, file exchange support, documentation, and integration guidelines. The customer's system remains the source of truth — TWC does not own or duplicate business data. It reads from source systems, transforms data into wallet-compatible content, and feeds wallet analytics back into the customer's ecosystem. ## If your software is not listed You can still integrate with The Wallet Crew even when no native connector exists. Use this sequence: 1. Start from the integration model and identify where your source data lives. 2. Decide whether a built-in connector is enough or a custom connector is needed. 3. Implement runtime scripting only for the parts that are truly specific to your stack. ### Main integration model The integration model stays the same for all projects: 1. Your system remains the source of truth for business data. 2. TWC stores identifiers and wallet-facing operational data. 3. TWC reads and transforms source data into Apple Wallet and Google Wallet payloads. 4. Wallet lifecycle events and analytics can be pushed back to your systems. This model avoids data duplication while keeping wallet experiences up to date. ### Choose your integration path | Situation | Recommended path | | ---------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Your software already has a documented connector | Use the connector page in this section | | Your software has no connector, but your APIs and events are available | Use [Custom connector](/connectors/custom-connector.md) | | Your integration mostly needs runtime behavior (data fill hooks, install/uninstall hooks, script email delivery) | Start with [Custom connector](/connectors/custom-connector.md) and continue in [Developer custom connectors guide](https://github.com/TheWalletCrew/docs/tree/main/developers/guides/integration-guides/custom-connectors.md) | ### Responsibilities | Responsibility area | Customer / partner system | The Wallet Crew | | ------------------------------ | ------------------------------------------------ | ------------------------------------------------ | | Business data ownership | Owns CRM/POS/ticketing/e-commerce records | Does not replace source systems | | Identifier strategy | Defines stable identifiers shared across systems | Uses identifiers to resolve and update pass data | | Wallet payload generation | Provides source fields and business rules | Maps data to Apple/Google wallet formats | | Pass delivery and updates | Triggers source events and change inputs | Orchestrates wallet updates and pass lifecycle | | Optional integration scripting | Implements project-specific API/event logic | Provides runtime hooks and execution context | The cards below cover each connector family. ## CRM, loyalty, and ticketing connectors

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.thewalletcrew.io/connectors/overview.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
