How to add custom Search Attributes to Workflow Executions at start time in Go

Provide key-value pairs in StartWorkflowOptions.SearchAttributes.

Search Attributes are represented as map[string]interface{}. The values in the map must correspond to the Search Attribute's value type:

• Bool = bool
• Datetime = time.Time
• Double = float64
• Int = int64
• Keyword = string
• Text = string

If you had custom Search Attributes CustomerId of type Keyword and MiscData of type Text, you would provide string values:

func (c *Client) CallYourWorkflow(ctx context.Context, workflowID string, payload map[string]interface{}) error {
    // ...
    searchAttributes := map[string]interface{}{
        "CustomerId": payload["customer"],
        "MiscData": payload["miscData"]
    }
    options := client.StartWorkflowOptions{
        SearchAttributes:   searchAttributes
        // ...
    }
    we, err := c.Client.ExecuteWorkflow(ctx, options, app.YourWorkflow, payload)
    // ...
}
