Schedule messages from process builder
We have two types of schedules to send messages from process builder.
Sender ID *→ for now you can use 15415161800 for testing purposes
Number * →Reference > Mobile Number field from contact
Template ID * → Template id must be in this format "T00001"
Related to * → Related record id to load merge fields.
As the name suggests this schedule type is dependent on time. In this schedule, we can send SMS on specific time like 10:30 AM.
Sender ID * →You can find your sender id at Salesforce > ValueText from app menu > Senders tab
Mobile Number Field* → must be API name field like below (it will take update phone number from the API Field Name)
Template ID* → template id must be in this format "T0001"
Related to * → related record id to load merge fields.
Start time * → choose pick list value for the time or you can write formula to pass dynamic value.
Start date * choose formula and build your own logic like (ex: send 2 days before meeting date then your formula would be "API name of the field - 2")
Action Type *Schedule
Frequency * Only once (If you want to set recurring schedule then take another value and you have to include END DATE in the field to stop the recursive messages)
END DATE→ required if the frequency type is not equal to “Only once”
Time zone→ (Must be ValueText or Salesforce supported format Ex: return values of UserInfo.getTimeZone().getID() method)
