# Stitch Connect Glossary

#### Client account access token

An API access token associated with a single Stitch client account. This token must be passed into the header of every request made to the API for the Stitch client account.

A client account access token is prefixed with `ac_` so as not to be confused with [partner credentials](https://help.qlik.com/en-US/stitch/developers/stitch-connect/guides/glossary#partner-credentials-term).

#### Connection check

A test performed by Stitch that checks the configuration of a source’s connection parameters.

#### Destination

Destination is the Stitch word for ‘data warehouse.’ A data warehouse is a central repository for data accumulated from a variety of sources.

#### Discovery

The first step in the replication process, this process takes place during the Extraction phase of a replication job. Discovery detects the tables and columns available in the source, along with any changes to the structure of those tables and columns.

#### Ephemeral token

**Note**: The Connect JavaScript client has been deprecated. [Learn more](https://help.qlik.com/en-US/stitch/changelog#2021-07-14-stitch-connect-javascript-stitch-js-deprecation).

A token that is passed to the Connect JavaScript client to create a session in the Stitch web application. This credential is created by using the [Create a session endpoint](https://help.qlik.com/en-US/stitch/developers/stitch-connect/api#sessions) in the Connect API.

A session is for the user for whom the API access token was created. The session will expire once terminated or after 12 hours.

#### Partner

An organization that utilizes Stitch Connect to programmatically create and/or manage Stitch client accounts on behalf of their users.

#### Partner ID

The unique ID for your partner application, obtained after an [interest form](https://www.stitchdata.com/contact/) is submitted to and approved by Stitch.

A partner ID is prefixed with `oc_` so as not to be confused with a [client account access token](https://help.qlik.com/en-US/stitch/developers/stitch-connect/guides/glossary#client-account-access-token-term).

#### Partner credentials

A set of credentials specific to a Stitch [partner](https://help.qlik.com/en-US/stitch/developers/stitch-connect/guides/glossary#partner-term), consisting of a [partner ID](https://help.qlik.com/en-US/stitch/developers/stitch-connect/guides/glossary#partner-id-term) and [partner key](https://help.qlik.com/en-US/stitch/developers/stitch-connect/guides/glossary#partner-key-term), obtained after an [interest form](https://www.stitchdata.com/contact/) is submitted to and approved by Stitch.

Partner credentials are used only to create Stitch client accounts. After the Stitch client account is created, the account’s [client access token](https://help.qlik.com/en-US/stitch/developers/stitch-connect/guides/glossary#client-account-access-token-term) is used to authenticate API requests.

#### Partner key

The key associated with your partner application, obtained after an [interest form](https://www.stitchdata.com/contact/) is submitted to and approved by Stitch.

A partner key is prefixed with `oc_` so as not to be confused with a [client account access token](https://help.qlik.com/en-US/stitch/developers/stitch-connect/guides/glossary#client-account-access-token-term).

#### Replication job

The three-step process by which Stitch replicates data. A replication job includes three distinct steps: Extraction, preparation, and loading.

#### Session

A browser session in the Stitch web application.

#### Source

A database, API, or other data application that Stitch replicates data from. Outside of Connect, known as an ‘integration’.

#### Stitch client account

An individual account for the Stitch web application.

#### Stream

A table in a [data source](https://help.qlik.com/en-US/stitch/developers/stitch-connect/guides/glossary#source-term).

#### Structure sync

The first step in the replication process, this process takes place during the Extraction phase of a replication job. A structure sync detects the tables and columns available in the source, along with any changes to the structure of those tables and columns. This is also referred to as [discovery](https://help.qlik.com/en-US/stitch/developers/stitch-connect/guides/glossary#discovery-term).
