In Nexla, App Store Connect data sources can be created using pre-built endpoint templates, which expedite source setup for common App Store Connect endpoints. Each template is designed specifically for the corresponding App Store Connect endpoint, making source configuration easy and efficient.
• To configure this source using a template, follow the instructions in Configure Using a Template.App Store Connect sources can also be configured manually, allowing you to ingest data from App Store Connect endpoints not included in the pre-built templates or apply further customizations to exactly suit your needs.
• To configure this source manually, follow the instructions in Configure Manually.
Configure Using a Template
Nexla provides pre-built templates that can be used to rapidly configure data sources to ingest data from common App Store Connect endpoints. Each template is designed specifically for the corresponding App Store Connect endpoint, making data source setup easy and efficient.
Endpoint Settings
-
Select the endpoint from which this source will fetch data from the Endpoint pulldown menu. Available endpoint templates are listed in the expandable boxes below. Click on an endpoint to see more information about it and how to configure your data source for this endpoint.
Endpoint Testing
Once the selected endpoint template has been configured, Nexla can retrieve a sample of the data that will be fetched according to the current settings. This allows users to verify that the source is configured correctly before saving.
-
To test the current endpoint configuration, click the Test button to the right of the endpoint selection menu. Sample data will be fetched & displayed in the Endpoint Test Result panel on the right.
-
If the sample data is not as expected, review the selected endpoint and associated settings, and make any necessary adjustments. Then, click the Test button again, and check the sample data to ensure that the correct information is displayed.
Configure Manually
App Store Connect data sources can be manually configured to ingest data from any valid App Store Connect API endpoint. Manual configuration provides maximum flexibility for accessing endpoints not covered by pre-built templates — for example, beta groups, TestFlight testers, in-app purchases, customer reviews, or any newly released endpoint.
With manual configuration, you can also create more complex App Store Connect sources, such as sources that use chained API calls — for example, listing apps and then fetching builds, App Store versions, or analytics report instances for each.
API Method
-
To manually configure this source, select the Advanced tab at the top of the configuration screen.
-
Select the API method that will be used for calls to the App Store Connect API from the Method pulldown menu. Most App Store Connect read endpoints use GET:
- GET: For retrieving resources, lists, or relationships
- POST: For creating resources (typically used in destinations, but available here for chained source calls)
- PATCH: For partial updates to resources
- DELETE: For removing resources
API Endpoint URL
- Enter the URL of the App Store Connect API endpoint from which this source will fetch data in the Set API URL field. All App Store Connect API URLs use the base
https://api.appstoreconnect.apple.com/v1/followed by the resource path (for example,https://api.appstoreconnect.apple.com/v1/apps).
Ensure the API endpoint URL is correct and accessible with your current credentials. You can test the endpoint using the Test button after configuring the URL.
Date/Time Macros (API URL)
Optionally, the API URL can be customized using macros—all macros added to the API URL will be converted into values when Nexla executes the API call. Macros are dynamic placeholders that allow you to create flexible API endpoints that adapt to different time periods. They are particularly useful for App Store Connect endpoints that take a filter[reportDate], filter[date], or similar date filter — most notably the Sales and Trends and Finance report endpoints.
Macros are particularly useful for APIs that require date ranges or other dynamic values that change between data ingestion runs. For example, use {now-1} with a Day time unit and a YYYY-MM-DD date format to always fetch yesterday's daily sales report.
-
To add a macro, type
{at the appropriate position in the API URL (within the Set API URL field), and select the desired macro from the dropdown list.-
{now}– The current datetime -
{now-1}– The datetime one time unit before the current datetime -
{now+1}– The datetime one time unit after the current datetime -
custom– Datetime macros can reference any number of time units before or after the current datetime—for example, enter(now-4)to indicate the datetime four time units before the current datetime
-
-
Select the format that will be applied to datetime macros from the Date Format for Date/Time Macro pulldown menu. App Store Connect typically expects
YYYY-MM-DDfor daily report dates,YYYY-MMfor monthly/finance report dates, andYYYYfor yearly report dates, so the selected format must match the endpoint being called. -
Select the datetime unit that will be used to perform mathematical operations in the included macro(s) from the Time Unit for Operations pulldown menu—for example, for the macro
{now-1}, whenDayis selected,{now-1}will be converted to the datetime one day before the current datetime.
Lookup-Based Macros (API URL)
Column values from existing lookups can also be included as macros in the API URL. Lookup-based macros allow you to reference data from previously configured data sources or lookups, enabling dynamic API endpoints that adapt based on existing data. For App Store Connect, this is useful when you have a Nexla dataset of app IDs, build IDs, certificate IDs, or version IDs and want to fetch the related resource for each.
Lookup-based macros are useful when you need to create App Store Connect URLs that reference specific IDs from another data source — for example, fetching the latest build details for every app ID returned by a /v1/apps source.
-
To include a lookup column value macro, select the relevant lookup from the Add Lookups to Supported Macros pulldown menu.
-
Type
{at the appropriate position in the API URL, and select the lookup column-based macro from the dropdown list. Lookup-based macros are automatically populated into the macro list when a lookup is selected in the Add Lookups to Supported Macros pulldown menu.
Path to Data
If only a subset of the data returned by an App Store Connect endpoint is needed, you can designate the part(s) of the response that should be included in the Nexset(s) by specifying the path to the relevant data within the response.
App Store Connect follows the JSON:API specification: list endpoints (such as /v1/builds or /v1/users) return an array of resources under the top-level data key, so the path to data is $.data[*]. Single-resource endpoints (such as /v1/builds/{'{id}'}) return a single object under data, so the path is $.data.
Path to Data is essential when API responses have nested structures. Without specifying the correct path, Nexla might not be able to properly parse and organize your data into usable records.
-
To specify which data should be treated as relevant in responses from this source, enter the path to the relevant data in the Set Path to Data in Response field.
- For responses in JSON format enter the JSON path that points to the object or array that should be treated as relevant data. JSON paths use dot notation (for example,
$.data[*]to access every element of the top-leveldataarray, or$.datafor a single-object response).
Path to Data Example:For an App Store Connect list endpoint (such as
GET /v1/builds), enter$.data[*]as the path to data. For a single-resource endpoint (such asGET /v1/builds/{'{id}'}), enter$.data. For Sales/Finance report endpoints that return a gzipped TSV file, no path is needed — the response is parsed as a delimited file. - For responses in JSON format enter the JSON path that points to the object or array that should be treated as relevant data. JSON paths use dot notation (for example,
Autogenerate Path Suggestions
Nexla can also autogenerate data path suggestions based on the response from the API endpoint. These suggested paths can be used as-is or modified to exactly suit your needs.
-
To use this feature, click the Test button next to the Set API URL field to fetch a sample response from the API endpoint. Suggested data paths generated based on the content & format of the response will be displayed in the Suggestions box below the Set Path to Data in Response field.
-
Click on a suggestion to automatically populate the Set Path to Data in Response field with the corresponding path. The populated path can be modified directly within the field if further customization is needed.

Metadata
If metadata is included in the response but is located outside of the defined path to relevant data, you can configure Nexla to include this data as common metadata in each record. App Store Connect responses typically include sibling top-level keys (such as meta.paging.total, links.self, links.next, and included) alongside the data array, and this setting can be used to preserve any of those values with each record.
A common pattern is to set Path to Metadata in Response to $.meta to capture the paging information returned with each list call, or to $.links to capture cursor URLs for downstream auditing.
-
To specify the location of metadata that should be included with each record, enter the path to the relevant metadata in the Path to Metadata in Response field.
- For responses in JSON format, enter the JSON path to the object or array that contains the metadata.
Request Headers
-
If Nexla should include any additional request headers in API calls to this source, enter the headers & corresponding values as comma-separated pairs in the Request Headers field (for example,
header1:value1,header2:value2).You do not need to include any headers already present in the credentials. The
Authorization: Bearer <jwt>header is added automatically based on your App Store Connect credential. The most common header to add here isAccept: application/vnd.apple.xcode-metrics+jsonwhen calling the perfPowerMetrics endpoint, orAccept: application/a-gzipwhen downloading salesReports or financeReports.
Endpoint Testing
After configuring all settings for the selected endpoint, Nexla can retrieve a sample of the data that will be fetched according to the current configuration. This allows users to verify that the source is configured correctly before saving.
-
To test the current endpoint configuration, click the Test button to the right of the endpoint selection menu. Sample data will be fetched & displayed in the Endpoint Test Result panel on the right.
-
If the sample data is not as expected, review the selected endpoint and associated settings, and make any necessary adjustments. Then, click the Test button again, and check the sample data to ensure that the correct information is displayed.
Save & Activate the Source
- Once all of the relevant steps in the above sections have been completed, click the Create button in the upper right corner of the screen to save and create the new App Store Connect data source. Nexla will now begin ingesting data from the configured endpoint and will organize any data that it finds into one or more Nexsets.
