Distance Calculator<\/p><\/div><\/figure>\n
Ever since the changes have taken place, I am getting many questions from LEM readers that this tool does not work for them anymore.<\/p>\n
Therefore, I thought to write this article to explain to you more in detail.<\/p>\n
In the previous article, I have simply shared a simple VBA code to call Distance matrix API – where no authentication (API Key) was required…<\/em><\/strong><\/p>\n After that change, the tool I had created and an article I had published was not working. Although I had replied via comments many times, I keep getting this question again and again. Therefore, I decided to write this article to answer all the questions at once.<\/p>\n Now, In order to invoke Distance matrix API from Google, first, you need to get an API key using your google account. For that matter, in order to access any of its APIs, you need to get an API key to authenticate your API calls.<\/p>\n You can follow the simple steps given here in this article from google – https:\/\/developers.google.com\/maps\/documentation\/distance-matrix\/get-api-key<\/a>. Before, you try to call the API from Excel VBA, get this API key for yourself.<\/p>\n As I mentioned previously, it is no longer for free (100%), you will have some limitations by using your FREE account. more details can be found here<\/a><\/p>\n As you have learned in the previous article about how to create different parameters before your make an API call, that remains exactly the same except for the fact that now you need to append &key=YOUR_API_KEY<\/em><\/strong><\/p>\n For example: <\/strong>Here is how a sample URL looks like using an API key<\/p>\n There are Two things: <\/strong><\/p>\n In the code, I have added an exception handling, so that you know what is wrong with the API call. It was my mistake that in my previous article, I did not use any exception handling, therefore it was not clear what exactly the problem is.<\/p>\n Secondly, I have added a placeholder for your API key which you can store in the config sheet and the tool is ready for your own use.<\/p>\n Here is the VBA code to call Google Distance Matrix API and get the distance and time taken :<\/p>\n <\/p>\n [\/et_pb_text][et_pb_cta title=”Distance Calculator Tool” button_url=”\/excel\/wp-content\/downloads\/Google-Distance-Calculator.xlsm” button_text=”Download FREE Workbook” admin_label=”FreeDownload-Sidebar-part-2″ _builder_version=”4.17.6″ _module_preset=”a50a16dd-d05f-4ea2-acab-1468d2e4010e” link_option_url_new_window=”on” button_letter_spacing_hover=”1px” saved_tabs=”all” global_colors_info=”{}” button_one_text_size__hover_enabled=”off” button_two_text_size__hover_enabled=”off” button_one_text_color__hover_enabled=”off” button_two_text_color__hover_enabled=”off” button_one_border_width__hover_enabled=”off” button_two_border_width__hover_enabled=”off” button_one_border_color__hover_enabled=”off” button_two_border_color__hover_enabled=”off” button_one_border_radius__hover_enabled=”off” button_two_border_radius__hover_enabled=”off” button_one_letter_spacing__hover_enabled=”off” button_two_letter_spacing__hover_enabled=”off” button_one_bg_color__hover_enabled=”off” button_two_bg_color__hover_enabled=”off”]<\/p>\n Before you run this excel sheet, you need to get your API key generated from your google account and put that key in the excel sheet at a specified place and then enjoy using it.<\/p>\n [\/et_pb_cta][et_pb_blurb title=”Suggested articles” use_icon=”on” font_icon=”||fa||900″ admin_label=”Blurb” _builder_version=”4.17.6″ _module_preset=”0249c68e-4de8-4f44-84ff-a9b1850785b6″ global_colors_info=”{}”]<\/p>\n [\/et_pb_blurb][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n<\/span>","protected":false},"excerpt":{"rendered":" Hi guys, on June 2016, google made some changesaround pricing and authentication etc. of its FREE APIs.Distance calculator API was also affected by those changes.
