What are Source Settings?

Source settings determine:

How a Source appears to your tenants
How you and your tenants authenticate to the Source
How Hotglue will run this Source

Example Source Settings

Understanding the Source Fields

`tap`

The tap field is a unique identifier for the source. It is used internally to reference the source and should be unique across all sources.

`label`

The label field is a human-readable name for the source. This is the name that will be displayed in the user interface.

`icon`

The icon field is a URL to an image that represents the source. This icon will be displayed in the user interface alongside the source’s label.

`tags`

The tags field is an array of strings that categorize the source. These tags can be used to filter and search for sources.

`domain`

The domain field specifies the primary domain associated with the source. This is typically the domain of the service the source integrates with.

`type`

The type field specifies the authentication method used by the source. Accepted values are oauth and api

`isForked`

The isForked field indicates whether this source has been modified from the default hotglue source settings.

`validation_supported`

The validation_supported field (boolean) indicates whether the connector validates a tenant’s credentials during account linking.

`install_uri`

The install_uri field can be used to overwrite the default git repo that the Tap will be installed from:

"install_uri": "git+https://github.com/your-org/tap-googleads.git@v1.2.4"

You can also override the install_uri for particular tenants by instead using:

"install_uri": {
  "env": "git+..." // Default install URI,
  "tenant": {
    "TENANT_ID": "git+..." // Install URI for particular tenant
  }
}

`is_private_repo`

The is_private_repo field tells hotglue to use your configured git access token when installing your Tap.

"install_uri": "git+https://github.com/your-org/tap-googleads.git@v1.2.4" // Private Repository
"is_private_repo": true

`formattable_fields`

The formattable_fields flag allows you to set a list of config flags that can be used as variables for your auth URLs.

"formattable_fields": ["shop", "tenant_id"]

For example, if you set:

"auth_url": "https://{shop}.shopify.com/token"

And the tenant has config:

{
  ...
  "shop": "usa",
  ...
}

then hotglue will use the following auth_url when completing the OAuth flow:

https://usa.shopify.com/token

All fields specified in the connect_ui_params are used as formattable_fields by default.

`version`

The version field allows you to add a chip to the Widget UI that specifies the source version.

"version": "v2"

`tap_url`

The tap_url field specifies the OAuth authorization URL used to initiate the authentication flow for this source. This is the URL the tenant is redirected to when connecting the source.

"tap_url": "https://app.example.com/oauth/authorize?response_type=code"

`auth_url`

The auth_url field specifies the OAuth token exchange URL used to obtain access tokens after the tenant has authorized the source.

"auth_url": "https://app.example.com/oauth/token"

`revoke_url`

The revoke_url field specifies the URL called to revoke OAuth tokens when a tenant disconnects the source.

"revoke_url": "https://app.example.com/oauth/revoke"

`dynamic_urls`

The dynamic_urls field allows the source to construct URLs dynamically at runtime using tenant-specific config values. When set to true, placeholders in tap_url and auth_url are replaced with values from the tenant’s config. For example, Amazon Advertising uses a region-specific URL selected by the tenant:

"tap_url": "{uri}/ap/oa?response_type=code&scope=advertising::campaign_management",
"auth_url": "{uri}/auth/o2/token",
"dynamic_urls": true,
"connect_ui_params": {
    "uri": {
        "label": "Amazon Ads Region",
        "description": "The region of the Amazon Ads account to connect",
        "type": "select",
        "options": [
            { "name": "North America (NA)", "value": "https://www.amazon.com" },
            { "name": "Europe (EU)", "value": "https://www.amazon.co.uk" }
        ]
    }
}

When a tenant selects EU, hotglue replaces {uri} with https://www.amazon.co.uk in the tap and auth URLs automatically.

`flowType`

The flowType field specifies how the source can be used across flows. When set to all, the source can be used in both tap and target flows.

"flowType": "all"

`no_fieldmap`

The no_fieldmap field disables field mapping for this source.

"no_fieldmap": true

`disabled`

The disabled field marks this source as disabled and unavailable for use.

"disabled": true

`connector_repo`

The connector_repo field specifies the git repository URL for a hotglue-maintained tap. This field only works with hotglue-maintained repositories.

"connector_repo": "git+https://github.com/hotgluexyz/tap-example.git"

`connector_tag`

The connector_tag field specifies the version tag of a hotglue-maintained tap repository to install. This field only works with hotglue-maintained repositories.

"connector_tag": "^v1.0.0"

`connector_type`

The connector_type field specifies the tap runtime type.

"connector_type": "airbyte"

`external_repo_url`

The external_repo_url field specifies the URL to the external repository for airbyte-sourced taps.

"external_repo_url": "https://github.com/airbytehq/airbyte/tree/master/airbyte-integrations/connectors/source-example"

`unified_version`

The unified_version field specifies the unified schema version used by this source.

"unified_version": "v2"

`basic_client_credentials`

The basic_client_credentials field uses HTTP Basic Auth for client credentials instead of standard OAuth.

"basic_client_credentials": true

`oauth_settings`

The oauth_settings field contains advanced OAuth configuration for the source. The following sub-fields are supported:

Field	Type	Description
`use_pkce_verifier`	boolean	Enables PKCE (Proof Key for Code Exchange) for enhanced OAuth security
`use_basic_auth`	boolean	Sends client credentials using HTTP Basic Auth during token exchange
`use_json_payload`	boolean	Sends the token request as a JSON payload instead of form-encoded data
`no_code_param`	boolean	Omits the code parameter from the token request for non-standard OAuth flows
`encode_state`	boolean	Encodes the OAuth state parameter before sending

"oauth_settings": {
    "use_pkce_verifier": true
}

`connect_ui_params`

The connect_ui_params field defines the fields shown to tenants in the connection UI. Each field key maps to a parameter object that supports the following properties:

Property	Type	Description
`label`	string	Human-readable label shown to the tenant for this field
`description`	string	Helper text displayed below the field to guide the tenant
`type`	string	Input type for the field. Accepted values: `password`, `boolean`, `select`, `number`, `list`, `multiline`. Defaults to text if not specified
`required`	boolean	Whether this field is required for the tenant to connect. Defaults to `true` if not specified
`adornment`	object	Adds prefix or suffix text around the input field
`adornment.start`	string	Text displayed before the input field (e.g. `https://`)
`adornment.end`	string	Text displayed after the input field (e.g. `.myshopify.com`)
`options`	array	Used when `type` is `select`. Defines the list of options the tenant can choose from
`options[].name`	string	Display name for the select option
`options[].value`	string	Value submitted when this option is selected
`params`	object	Used when `type` is `list`. Defines the sub-fields for each item in the list

The following examples show fields using different property combinations:

"connect_ui_params": {
    "shop": {
        "label": "Shop",
        "description": "Your shop name",
        "adornment": {
            "start": "https://",
            "end": ".myshopify.com"
        }
    },
    "region": {
        "label": "Region",
        "type": "select",
        "options": [
            { "name": "North America", "value": "https://www.amazon.com" },
            { "name": "Europe", "value": "https://www.amazon.co.uk" }
        ]
    },
    "bulk": {
        "label": "Bulk",
        "type": "boolean",
        "required": false
    },
    "api_key": {
        "label": "API Key",
        "description": "Your API Key",
        "type": "password"
    }
}

`connector_props`

The connector_props field contains additional configuration properties for the tap. The following sub-fields are supported:

Field	Type	Description
`singer_sdk`	boolean	Indicates this tap is built using the Singer SDK
`static_data`	boolean	Indicates this tap handles arbitrary file-based data sources such as file storage, Google Drive, or blob storage
`validation_disabled`	boolean	Disables credential validation for this tap during account linking

"connector_props": {
    "singer_sdk": true
}

`config`

The config block defines default configuration values that are automatically applied to every new tenant connecting to this source. Tenants inherit these values without needing to configure them manually. The only universal config field supported across all sources is start_date. All other config fields are source-specific — refer to the individual source’s documentation for the full list of supported fields.

Field	Type	Description
`start_date`	string	Default start date for data sync in ISO 8601 format

"config": {
    "start_date": "2000-01-01T00:00:00.000Z"
}
