Ok, yes, you can use a Custom Action in AJO to call an external API (i.e., Target Recommendations API) during the journey flow. The response from that API can then be mapped to journey attributes and used for personalization in email templates later in the journey, BUT here are the caveats:
- The journey’s timeline now includes the external API’s response time. For high volumes, this may impact throughput.
- You need to make sure the email template references the correct path to the recommendations; the path must be created each time.
