# Standard Practices

- [General Info](https://developer.emporix.io/api-references/standard-practices/general-info.md): The Emporix API follows standardized practices for data consistency, using ISO and IETF formats for countries, currencies, dates/times, and languages across its services.
- [Mixins](https://developer.emporix.io/api-references/standard-practices/mixins.md): Mixins let you extend business resources with custom properties by defining JSON schemas, hosting them, and referencing them in resource metadata for flexible, schema-driven data enrichment.
- [Query Parameter](https://developer.emporix.io/api-references/standard-practices/q-param.md): You can use a standard q-param to filter search by string, localized, or numeric field values using exact matches, comparisons, and ranges.
- [Translations](https://developer.emporix.io/api-references/standard-practices/translations.md): Translations use language-code maps, enabling objects to be created, retrieved, and updated in one or multiple languages.
- [Custom ID](https://developer.emporix.io/api-references/standard-practices/custom-id.md): Custom IDs allow external systems to use their own identifiers as references for key entities, ensuring consistent relationships across systems.
- [Upsert](https://developer.emporix.io/api-references/standard-practices/upsert.md): Upsert in Emporix simplifies entity management by allowing a PUT request to either create a new record if it doesn’t exist or update it if it does.
- [B2B Token](https://developer.emporix.io/api-references/standard-practices/b2btoken.md): The B2B Token embeds a customer’s selected legal entity in their authorization token, enabling consistent access control and data visibility without re-login.
- [Bulk Request Limits](https://developer.emporix.io/api-references/standard-practices/bulk-request-limits.md): Bulk request limits for Emporix API endpoints that support multiple changes in a single request.
