Depending on your setup, data should flow between Google Dialogflow ES and OCR Space (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect Google Dialogflow ES and OCR Space
Google Dialogflow ES + OCR Space + Google Sheets: When a user submits an image via Dialogflow, the image is sent to OCR Space to extract the text. The extracted text is then recorded in a new row in Google Sheets.
Gmail + OCR Space + Google Dialogflow ES: When a new email arrives with an attachment, OCR Space converts the attached invoice image into text. Google Dialogflow ES analyzes the text to answer customer queries about invoice data by detecting the intent from the extracted text.
