# 📘 Glossary

It is important to keep it simple, so we created this glossary to clarify some basic Open Banking concepts.

### General Concepts

***

**API:** is an Application Programming Interfaces. The API allows your company´s system to communicate with the financial institution´s system.

**Connect widget:** The Connect Widget is the tool through which your clients will connect their institution accounts within your app. This way you will be able to query your client´s information.

**API call:** an API call is made each time you request financial information to Datanomik API.

**Sync call**: A sync call is made each time Datanomik requests financial information from the financial institution.

**API keys:** are your credentials to access Datanomik API.

**Link:** is a set of credentials (such as username and password) to access your account.

**Type of Link**

1. **Recurrent link:** is used to access an account in a recurrent way. Datanomik will inform you when there are any changes in your account.
2. **One-shot link:** is used only once to access an account.

**Postman:** is an application used for API testing. It is an HTTP client that tests HTTP requests, utilizing a graphical user interface, through which we obtain different types of responses that need to be subsequently validated.

### Resources

***

**Accounts:** account of your financial institution.

**Balances:** the account balance.

**Owners:** financial institution account owner.

**Users:** user(s) who can access the account of a financial institution.

**Transactions:** the transactions made in your account.

**Assets:** consolidates all the information in one link (account, balances, owners, users)

### Date Fields

***

**date:**  bank´s processing date. Format: ISO 8601

**created\_at** : date when the account was created in Datanomik.

**acceded\_at:** last time the information was updated.

**updated\_at:** date that any information about a resource was updated. For example, it is used when the financial institution´s credentials are updated.

### HTTP Verbs

***

**Endpoint:** is the group of HTTP methods used to make different queries of financial information.
