if i have flow and a trigger what will execute first and what is the correct order of execution in salesforce?

Hi
If it run before the record is saved then the record-triggered flow executes first and after that before triggers executes. If it run after the record is saved then the after trigger executes first and after that the record-triggered flow executes. For information you can check on below link

Please mark it as best answer if this helps

Thanks

Hello Rohit ,

In Salesforce, actions are executed in a specific order. Here's a sample scenario: 

You want to set up an auto-response rule for email-to-case cases. You define the criteria as:

Order 1 - Criteria: Case: ABC Equals XYZ - Send from(Email): XYZ - Template: Auto response XYZ.
Order 2 - Criteria: Blank - Send from(Email): 2XYZ - Template: 2Auto response XYZ

Process Builder will trigger whenever EmailMessage Isincoming: True. Process Builder should update the Case field (ABC) with the XYZ value. 

You expect auto-response Order 1 to fire, but Order 2 fires instead. This is due to the order in which actions execute in Salesforce.

In Salesforce, this is the order in which actions execute:

1. System Validation Rules
2. Apex Before Triggers
3. Custom Validation Rules
4. Duplicate Rules
5. Apex After Triggers
6. Assignment Rules
7. Auto-Response Rules
8. Workflow Rules
9. Processes
10. Escalation Rules
11. Roll-Up Summary Fields
