Cross-Review of Technical Documentation for Active Pharmaceutical Ingredient and Pharmaceutical Intermediate Manufacturing: HTTP Interfaces and External Systems

Daily documents include batch production records, material balance records, reaction purification records, cleaning records, impurity profile reports

What data looks like for this category

Daily documents include batch production records, material balance records, reaction purification records, cleaning records, impurity profile reports, deviation and change documents. Data comes from registered process documents, raw material batch ledgers, DCS systems, weighing systems, LIMS, chromatography data systems, QMS. Data updates per production batch and process step. Fields include reaction temperature, feeding amount, impurity content, batch number, operation time, operator. Units include degrees Celsius, kilograms, milligrams per liter, and others.

Constraints Imposed on HTTP Interfaces and External Systems

Daily documents have complex structures, including structured process parameters and unstructured report content. HTTP interfaces must support multi-format data interaction. Multi-source data synchronization requires handling response delays from different industrial systems. Request timeout and retry policies must be configured. Data volume updated per batch has peak loads. Interface concurrent processing capacity must match production rhythms. Data involves process and compliance information. Interface authentication and data encryption must meet production quality management requirements.

The following configurations are based on FastGPT v4.17.0.

How to Set Configurations

Configuration ItemRecommended SettingRationale
Authentication ConfigurationConfigure the Authorization header as a Bearer token. Set token validity based on actual measurementsAdapts to authentication rules for industrial systems such as LIMS and chromatography data systems
Request Timeout600 secondsMatches the response delay range of industrial equipment such as DCS and weighing systems
Single Request Data Volume800–1200 charactersAdapts to the length of single structured fields in batch production records
Variable Mapping RuleMap batch numbers and impurity content to the variables parameterEnables associated calls of cross-system data
Response Data ValidationValidate whether responseData contains batch number and impurity content fieldsEnsures returned data meets business compliance requirements

Three Common Mistakes

  • Symptom: A 400 Bad Request error is returned when performing cross-system multi-row data synchronization. Cause: Requests are not split by production batch. A single submission of multi-row cross-system query statements exceeds the interface's single data volume limit.
  • Symptom: Returned process review results do not include document citation sources, and no corresponding fields exist in responseData. Cause: Extraction logic for citation source fields is not configured. Batch numbers, impurity profile reports, and other items are not mapped to the variables parameter.
  • Symptom: Document content cannot be obtained after connecting to the Confluence knowledge base. Cause: Authentication information for the Authorization header is not correctly configured. The interface path rules for Confluence are not adapted.

How to Confirm the Configuration Is Correct

  • A synchronization request for a single batch production record is sent. The interface returns a 200 OK status code.
  • An impurity content query request is sent. The responseData field contains preset business fields.
  • A cross-system data associated call is sent. The batch number mapped in the variables parameter matches the source system ledger.
  • Synchronization requests for five consecutive production batches are sent. No consecutive errors occur.
