LookML (v1)

Last updated: 9/15/2026

LookML is in beta
LookML is currently in beta. The info in this guide is subject to change.

LookML is supported by the Singer community
This integration is powered by Singer's LookML tap. For support, visit the GitHub repo or join the Singer Slack.

LookML integration summary

Stitch’s LookML integration connects to GitHub repositories where your Looker LookML is hosted for your Looker project. Stitch then replicates it using GitHub v3 API to extract LookML components using lkml parser.

Refer to the Schema section for a list of objects available for replication.

Connecting LookML

LookML setup requirements

To set up LookML in Stitch, you need:

Access to the GitHub repositories you want to replicate data from. Stitch will only be able to access the same repositories as the user who creates the access token.

Step 1: Create access token

Sign into your GitHub account.
Click the User menu (your icon) > Settings.
Click Developer settings in the navigation on the left side of the page.
Click Personal access tokens.
On the Personal access tokens page, click the Generate a personal access token button. If prompted, enter your password.
In the Description field, enter stitch. This will allow you to easily idenfiy what application is using the token.
In the Select Scopes section, check the repo option:

Highlighted repo scopes on the GitHub Personal Access Tokens page

Note: While these are full permissions, Stitch will only ever read your data. The repo scope is required due to how GitHub structures permissions.
Click the Generate token button.
The new access token will display on the next page. Copy the token before navigating away from the page - GitHub won’t display it again.

Step 2: Add LookML as a Stitch data source

Sign into your Stitch account.
On the Stitch Dashboard page, click the Add Integration button.
Click the LookML icon.
Enter a name for the integration. This is the name that will display on the Stitch Dashboard for the integration; it’ll also be used to create the schema in your destination.

For example, the name “Stitch LookML” would create a schema called stitch_lookml in the destination. Note: Schema names cannot be changed after you save the integration.
In the API Token field, paste the access token you copied from step 1.
In the Git Owner field, enter the owner of the repositories you want to replicate. You can find this info in the repository’s URL. For example: The Git owner of https://github.com/stitch/stitch-repo would be stitch.

Note: While you can replicate data from multiple repositories, this integration only supports replicating from one owner at a time.
In the Git Repositories field, enter the repository or repositories you want to replicate. You can find this info in the repository’s URL. For example: The repository of https://github.com/stitch/stitch-repo would be stitch-repo.

To track multiple repositories, enter them as a comma-delimited list. For example: repo-1, repo-2.

Step 3: Define the historical replication start date

The Sync Historical Data setting defines the starting date for your LookML integration. This means that data equal to or newer than this date will be replicated to your data warehouse.

Change this setting if you want to replicate data beyond LookML’s default setting of 1 year. For a detailed look at historical replication jobs, check out the Syncing Historical SaaS Data guide.

Step 4: Create a replication schedule

Replication schedules affect the time Extraction begins, not the time to data loaded. Refer to the Replication Scheduling documentation for more information.

In the Replication Frequency section, you’ll create the integration’s replication schedule. An integration’s replication schedule determines how often Stitch runs a replication job, and the time that job begins.

LookML integrations support the following replication scheduling methods:

Replication Frequency
Anchor Scheduling
Advanced Scheduling using Cron (Advanced or Premium plans only)

To keep your row usage low, consider setting the integration to replicate less frequently. See the Understanding and Reducing Your Row Usage guide for tips on reducing your usage.

Step 5: Set objects to replicate

Is an object missing or not replicating? Verify that the object meets the requirements for selection and replication.

The last step is to select the tables and columns you want to replicate. Learn about the available tables for this integration.

Note: If a replication job is currently in progress, new selections won’t be used until the next job starts.

For LookML integrations, you can select:

Individual tables and columns
All tables and columns

Click the tabs to view instructions for each selection method.

In the integration’s Tables to Replicate tab, locate a table you want to replicate.
To track a table, click the checkbox next to the table’s name. A blue checkmark means the table is set to replicate.
To track a column, click the checkbox next to the column’s name. A blue checkmark means the column is set to replicate.
Repeat this process for all the tables and columns you want to replicate.
When finished, click the Finalize Your Selections button at the bottom of the screen to save your selections.

Important: Using the Select All feature will overwrite any previous selections. However, selections aren’t final until Finalize Your Selections is clicked. Clicking Cancel will restore your previous selections. Refer to the Select All guide for more info about this feature.

Click into the integration from the Stitch Dashboard page.
Click the Tables to Replicate tab.
In the list of tables, click the box next to the Table Names column.
In the menu that displays, click Track all Tables and Fields:

The Track all Tables and Fields menu in the Tables to Replicate tab
Click the Finalize Your Selections button at the bottom of the page to save your data selections.

Initial and historical replication jobs

After you finish setting up LookML, its Sync Status may show as Pending on either the Stitch Dashboard or in the Integration Details page.

For a new integration, a Pending status indicates that Stitch is in the process of scheduling the initial replication job for the integration. This may take some time to complete.

Initial replication jobs with Anchor Scheduling

If using Anchor Scheduling, an initial replication job may not kick off immediately. This depends on the selected Replication Frequency and Anchor Time. Refer to the Anchor Scheduling documentation for more information.

Free historical data loads

The first seven days of replication, beginning when data is first replicated, are free. Rows replicated from the new integration during this time won’t count towards your quota. Stitch offers this as a way of testing new integrations, measuring usage, and ensuring historical data volumes don’t quickly consume your quota.

Replication will continue after the seven days are over. If you’re no longer interested in this source, be sure to pause or delete the integration to prevent unwanted usage.

LookML table reference

Schemas and versioning

Schemas and naming conventions can change from version to version, so we recommend verifying your integration’s version before continuing.

The schema and info displayed below is for version 1 of this integration.

This is the latest version of the LookML integration.

Table and column names in your destination

Depending on your destination, table and column names may not appear as they are outlined below.

For example: Object names are lowercased in Redshift (CusTomERs > customers), while case is maintained in PostgreSQL destinations (CusTomERs > CusTomERs). Refer to the Loading Guide for your destination for more info.

model_files

The model_files table contains information about model files in your GitHub about using the Git API Search filename and extension filters for model and lkml.
