Transaction exchange platform with a validation microservice for validating transactions before being processed

A transaction exchange platform comprising:

• a screening microservice configured to analyze transaction objects received by the transaction exchange platform;
• a watchdog microservice configured to track transaction objects being processed by the transaction exchange platform;
• at least one processor;
• and
• memory storing instructions that, when executed by the at least one processor, cause the transaction exchange platform to:
• receive, by the screening microservice, a first transaction object corresponding to a first payment transaction, wherein the first transaction object comprises first transaction details;
• determine, by the screening microservice and using a predictive model trained to identify one or more errors, whether the first transaction details indicate that processing of the first transaction object is likely to fail;
• based on a determination that the first transaction details indicate a first likelihood that processing of the first transaction object is going to fail, determine a corrective action to reduce the first likelihood that processing of the first transaction object is going to fail;
• send, by the screening microservice to a first user device, an indication that processing of the first transaction object is likely to fail and the corrective action;
• receive, by the screening microservice from the first user device, a response indicating acceptance of the corrective action, wherein the corrective action is implemented based on receiving the response
• implement, by the watchdog microservice, the corrective action by updating addenda data associated with the first transaction object;
• and
• add, by the screening microservice, the first transaction object with updated addenda data to a streaming data platform, wherein adding the first transaction object to the streaming data platform comprises setting a current workflow stage of the first transaction object to an initialization stage.

One or more non-transitory computer readable media comprising instructions that, when executed, cause a computing device to:

• receive, by a screening microservice of a transaction exchange platform, a first transaction object corresponding to a first payment transaction, wherein the first transaction object comprises first transaction details;
• determine, by the screening microservice and using a predictive model trained to identify one or more errors, whether the first transaction details indicate that processing of the first transaction object is likely to fail;
• based on a determination that the first transaction details indicate a first likelihood that processing of the first transaction object is going to fail, determine a corrective action to reduce the first likelihood that processing of the first transaction object is going to fail;
• send, by the screening microservice to a first user device, an indication that processing of the first transaction object is likely to fail and the corrective action;
• receive, by the screening microservice from the first user device, a response indicating acceptance of the corrective action, wherein the corrective action is implemented based on receiving the response;
• implementing, by a watchdog microservice of the transaction exchange platform, the corrective action by updating addenda data associated with the first transaction object;
• and
• add, by the screening microservice, the first transaction object with updated addenda data to a streaming data platform, wherein adding the first transaction object to the streaming data platform comprises setting a current workflow stage of the first transaction object to an initialization stage.
