MailChimp Integration: Implementation Details

No rush on this!

I'd be grateful for a little clarification on the MailChimp Integration.

1. API Key - Should a new API Key be generated and used on each form? 

2. API Key - Do API Keys sometimes go bad? Or expire? 

3. API Key - Should/can you use the same API Key on MailChimp Integrations on different forms?

4. To what degree of changes to a form require removal/reintegration of MailChimp Integration? Minor change to text? Any changes to text associated with fields mapped to MailChimp? And so on, to changes in Properties, rearranging fields, etc. 

Thanks for what you do, it's much appreciated!

1. API Key - Should a new API Key be generated and used on each form? 

It's not necessary to use different API Key for each form when you integrate your form into MailChimp. You can use same API key for several forms. 

2. API Key - Do API Keys sometimes go bad? Or expire? 

Sometimes Mailchimp Integration fail due to expired API key used in the integration. If this happens, you can generate new API key. For more info about API keys please see this link: http://kb.mailchimp.com/integrations/api-integrations/about-api-keys

3. API Key - Should/can you use the same API Key on MailChimp Integrations on different forms?

Yes, you can use the same API key on MailChimp Integrations on different forms.

4. To what degree of changes to a form requires removal/reintegration of MailChimp Integration? Minor change to text? Any changes to text associated with fields mapped to MailChimp? And so on, to changes in Properties, rearranging fields, etc. 

If you have removed or deleted the fields on your form which are mapped to Mailchimp and if the data doesn't go to the MailChimp integration, then to fix this, you can re-integrate again Mailchimp on your form. How to Integrate with MailChimp
