# **Tag: connectors**

- [<h2>**How a connector works**</h2>

  The mechanics of a connector — the outbound half that polls, maps and publishes, the inbound bridge that answers identity questions, and the design rules the code holds you to.#connectors#sync#mapping#bridge#webhook#idempotency](https://openepcis.io/docs/connectors/how-a-connector-works)
- [<h2>**Identifiers: GTIN, SKU and What Identifies What**</h2>

  One product needs exactly one GS1 identifier — the GTIN. Where the connector finds it, why your SKU is a different thing, and how batch, serial and logistics-unit levels build on top.#connectors#gtin#sku#lgtin#sgtin#sscc#check-digit](https://openepcis.io/docs/connectors/identifiers-gtin-and-sku)
- [<h2>**The UnoPim connector**</h2>

  The whole UnoPim route — what has to exist in the PIM, how the connection is configured, what the first sync publishes, and where the data surfaces in DDM and on the published passport page.#connectors#unopim#pim#gtin#mapping#webhook#passport](https://openepcis.io/docs/connectors/unopim)
- [<h2>**Events, Credentials and Representations**</h2>

  What happens after a record is published — how a movement in your source system becomes an EPCIS event, where UNTP answers the same question differently, and how a passport gains a signed, selectively disclosed representation.#connectors#epcis#events#event-types#transformation#error-declaration#verifiable-credentials#untp#access-tiers#representations](https://openepcis.io/docs/connectors/events-credentials-and-representations)
- [<h2>**The Odoo connector, step by step**</h2>

  One warehouse day walked through end to end — goods in, packed onto a pallet, shipped, part of it back, the rest ground into another article, and one report taken back — with the screen and the EPCIS event it produces side by side.#connectors#odoo#epcis#events#sscc#aggregation#transformation#tutorial](https://openepcis.io/docs/connectors/odoo)
- [<h2>**Connectors**</h2>

  How the master data you already keep in a PIM or an ERP becomes two passport forms, a stream of EPCIS events and a resolvable GS1 Digital Link — and how far each connector has come.#connectors#unopim#odoo#erpnext#metasfresh#digital-product-passport#epcis#resolver](https://openepcis.io/docs/connectors)
