Prerequisites
Before you begin, make sure that:- Reporter runs and you can authenticate with its API.
- An operator has configured at least one data source for the data your template queries.
- You have a
.tplfile that matches the intended output format. For PDF output, author the template as HTML. See Template examples and the template reference.
Manage templates
Reporter uses uploaded.tpl files to define report content and layout.
Upload a template
Call Upload a template as a multipart request with all four required fields:template: the.tplfile.outputFormat: the generated file format, such asHTML,PDF,XML,CSV, orTXT.description: a human-readable description of the template.category: the report family, such ascadoc. Use lowercase letters, digits, underscores, and hyphens, up to 100 characters.
Maintain existing templates
Use the template endpoints to: Deleting a template is a soft delete. Reporter excludes it from standard queries but preserves reports already created from it.Generate a report with filters
Call Create a report with both required fields:templateId: the identifier returned when you uploaded the template.filters: the conditions grouped by data source, table, and field.
id field. Store this value as REPORT_ID to check the generation status and retrieve the output.
See Advanced filtering for the supported operators and filter structure.
Discover data source schemas
Inspect the configured data sources before building templates or dynamic filter interfaces:- List data sources returns a page of registered connections without credentials.
- Retrieve a data source returns one connection configuration by
dataSourceId. Credentials remain hidden. - Get a data source schema introspects the live tables or collections and their typed fields.
DATASOURCE_* variables at startup.
Interpret report statuses and errors
Call Check report status withREPORT_ID.
Treat
Finished and Final reports, and a Draft with no required field blank, as downloadable. A Partial result requires investigation even when Reporter produced some data.
Verify and download the report
When the status isFinished:
- Call Download a report with
REPORT_ID. - Confirm that the response has the expected content type and
Content-Dispositionheader. - Open the file and verify that its data and layout match the template and filters.
Troubleshooting
Operator configuration
The following deployment settings are for operators. Application users don’t need them for the report generation workflow.Configure object storage
Reporter stores templates and generated reports in one S3-compatible bucket. It uses thetemplates/ and reports/ prefixes. Reporter supports AWS S3, MinIO, and SeaweedFS.

MinIO (local development)
MinIO (local development)
SeaweedFS (local development)
SeaweedFS (local development)
S3 doesn’t support per-object TTL. Configure S3 bucket lifecycle policies if generated reports must expire automatically.
Configure external data sources
SetDATASOURCE_CRED_ENC_KEY to a persistent hexadecimal AES key before Reporter starts. Generate a 32-byte key with openssl rand -hex 32. Manager and worker fail startup when the key is absent or malformed. Keep the same key available to every Reporter runtime that reads the registry, because stored passwords are encrypted with it.
Use the API for the normal data-source lifecycle. In a self-hosted deployment, you may also seed PostgreSQL or MongoDB entries at startup with DATASOURCE_<NAME>_* variables:
For a source whose
CONFIG_NAME is midaz_onboarding:
CONFIG_NAME:
CONFIG_NAME. For example, external_db maps to DATASOURCE_EXTERNAL_DB_SCHEMAS:
database:schema.table in templates and schema.table as the filter table key:
public schema.
Manager and worker connect to a data source on demand, when a request needs it.
