What is it good for?

Address Auto Suggest (powered by Google Places API) allows to fill in shipping/billing address fields conveniently, using only a part of address as a base.

Fewer actions are needed to place an order. Moreover, you have less chance of receiving mistakes from the customer's side, which is also equal to less chance of Cart abandonment and misdirected shipping.

How it works?

Once a customer starts filling in the first address field, a dropdown with address choices will appear.

The proposed choices are based on a customer's actual location (the closest go first).

Once any of the proposed options is chosen, Country, City, Postcode, Address will be filled with selected data.

How it looks?

For Magento 1:

For Magento 2.1+:

How to enable it?

Please see this guideline!

API key is required To use Address Auto Suggest. Google account with enabled billing is necessary to obtain one.
To create an account on Google (if necessary), please use this guideline.
Then, please proceed to this page to create a new API key. ('Maps API' should be selected at first step).

• If you do have a project on Google Cloud, you can skip the abovementioned steps. For existing projects, API key can be created here.

Key is ready!

At your Magento instance's Backend, please open System > Configuration > Amasty Extensions > One Step Checkout , Google Autocomplete tab.

For Magento 1 version:

For Magento 2.1+ version:

Choose 'Yes' in the 'Enable' field and add the key below.

Flush cache - and, next time any customer would reach your Checkout, Address Auto Suggest will appear for them!

1. Basic troubleshooting

Address Auto Suggest is enabled but the drop-down menu doesn't appear. 'Enter a location' prompt doesn't appear in the Address field.

The problem is that the key has been added but not saved.

At System > Configuration > Amasty Extensions > One Step Checkout , Google Autocomplete tab please re-add your API key.

Then, 'Save' and flush the cache.

Upon reaching Checkout my browser displays location disclosure prompt.

Knowing customer's location is necessary to propose addresses nearest to him for auto suggesting.

For better privacy sake, however, a customer may decide not to share his location information with API - auto suggest results can be less precise in this case.

This behavior is being controlled from web browser's side.

Address Auto Suggest worked right after adding the key but ceased to work afterwards

Please check content of this page.

If you see only 'Add billing account' prompt here - it means that your Google account doesn't have Billing enabled, thus API calls limit for it is too short.

On enabling Billing.

If you have more than one project at Google - please make sure that your new Billing account is linked with proper project. It can be checked here.

After successful Billing creation & linking up to 15 minutes should pass - API call limit will become more adequate afterwards.

First Address line is blocked at Checkout.

Most frequent cause is a misprint in API key.

At System > Configuration > Amasty Extensions > One Step Checkout , Google Autocomplete tab please re-add the API key.

Then, 'Save' and flush cache.

2. Troubleshooting via browser's Console

Guideline to enable web browser's Console.

'Google Maps JavaScript API warning: SignedInNotSupported' error appeared in console.

This one is completely harmless, no additional actions required, shouldn't affect anything.

'Google Maps JavaScript API error: RefererNotAllowedMapError' (followed by 'Your site URL to be authorized' occasionally)

Case 1: this API key doesn't have Maps JavaScript API allowed in its configuration.

To allow Places API, please choose either

• to keep key's 'API restrictions' tab empty (to allow all API calls, handy for testing purposes)
• or to add Places API allowed here:

Case 2: this API key does have Maps JavaScript API allowed , but website URL (or other additional requirement imposted by Google) was not defined.

To solve it, please choose either

• to add [*] to this API key's 'HTTP referrers (websites)' permissions (will allow ALL websites to use this key, could be convenient for tests but not recommended)
• or to add [this_Magento_frontend_URL/*] instead of just [*] (to limit to this Frontend only).
