Hi everyone !
I am trying to authenticate a request using Basic Auth.
I then need to base64-encode my logins.
(could encode them manually and then insert but would prefer to keep that logic in the code)
I didn’t found how to achieve this “natively” without rewriting the entire encoding function.
btoa() does not seems to work 
Can anyone help me on this ?
Thanks
Can’t really say what the issue is without seeing the scripting context. Is this in a Script Block? Scrip automation? Custom App? External script accessing via the Airtable API?
If you want to learn more, you have to share the details.

Thank you for your reply.
I am trying to fetch from a Script Block.

Okay - that’s helpful, but not likely enough to comment more than generally. Without seeing exactly what you’re trying to run through a base64 encoding process, we’re still in the dark.
Given that Script Blocks are everyday javascript, btoa() should work just fine unless there are some strange characters in the string being encoded…
btoa() accepts a “string” where each character represents an 8-bit byte – if you pass a string containing characters that can’t be represented in 8 bits, it will probably break. This isn’t a problem if you’re actually treating the string as a byte array, but if you’re trying to do something else then you’ll have to encode it first.

Actually, btoa() function is not found.
Tried window.btoa() as well with no success.
I don’t really know how this function is supposed to work in the context of Airtable Script Block.
It should probably be something else than window but can’t find what.
Even though I get the squiggly underlines under btoa, the code runs just fine when I use it.
There are enough times when squiggly red underlines appear for working code, that if the logic makes sense to me and the code runs, I ignore the squiggly red underlines.

Hmm… works fine for me:
Script…
output.markdown('## BtoA() Test');
output.markdown('### User/Password');
let pw = "bfg:123456";
output.inspect(pw);
output.markdown('### Base64 of User/Password');
let b64 = btoa(pw);
output.inspect(b64);Ok thank you, I didn’t try to run it…
I am not used to run the code when editor shows an error :grinning_face_with_sweat:
Thank you !
Just a followup note, while btoa() works for me in Scripting app (despite the squiggly red underline), it does not work for me in an automation action script.

This is why I was so careful to understand the scripting context. This is a possible out on the script action side.

But it seems well reading this thread that window. prefix is neither necessary nor globalThis. prefix !

When I tried to do this in 2022, I am getting a ReferenceError. Is there an updated recommendation on how to accomplish this? My implementation is similar to the below.
console.log(btoa("STRING_TO_ENCODE"))
... and in 2023 btoa() is still not supported within a Scripting Automation? 🤨 Most frustrating!
For Scripting Automation, here's a solution that works well for me.
function getBambooToken(client) {
let tokenizedString = <API_key> + ":x"
return btoa(tokenizedString)
}
function btoa(token) {
var Base64={_keyStr:"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=",encode:function(e){var t="";var n,r,i,s,o,u,a;var f=0;e=Base64._utf8_encode(e);while(f<e.length){n=e.charCodeAt(f++);r=e.charCodeAt(f++);i=e.charCodeAt(f++);s=n>>2;o=(n&3)<<4|r>>4;u=(r&15)<<2|i>>6;a=i&63;if(isNaN(r)){u=a=64}else if(isNaN(i)){a=64}t=t+this._keyStr.charAt(s)+this._keyStr.charAt(o)+this._keyStr.charAt(u)+this._keyStr.charAt(a)}return t},decode:function(e){var t="";var n,r,i;var s,o,u,a;var f=0;e=e.replace(/[^A-Za-z0-9\+\/\=]/g,"");while(f<e.length){s=this._keyStr.indexOf(e.charAt(f++));o=this._keyStr.indexOf(e.charAt(f++));u=this._keyStr.indexOf(e.charAt(f++));a=this._keyStr.indexOf(e.charAt(f++));n=s<<2|o>>4;r=(o&15)<<4|u>>2;i=(u&3)<<6|a;t=t+String.fromCharCode(n);if(u!=64){t=t+String.fromCharCode(r)}if(a!=64){t=t+String.fromCharCode(i)}}t=Base64._utf8_decode(t);return t},_utf8_encode:function(e){e=e.replace(/\r\n/g,"\n");var t="";for(var n=0;n<e.length;n++){var r=e.charCodeAt(n);if(r<128){t+=String.fromCharCode(r)}else if(r>127&&r<2048){t+=String.fromCharCode(r>>6|192);t+=String.fromCharCode(r&63|128)}else{t+=String.fromCharCode(r>>12|224);t+=String.fromCharCode(r>>6&63|128);t+=String.fromCharCode(r&63|128)}}return t},_utf8_decode:function(e){var t="";var n=0;var r=c1=c2=0;while(n<e.length){r=e.charCodeAt(n);if(r<128){t+=String.fromCharCode(r);n++}else if(r>191&&r<224){c2=e.charCodeAt(n+1);t+=String.fromCharCode((r&31)<<6|c2&63);n+=2}else{c2=e.charCodeAt(n+1);c3=e.charCodeAt(n+2);t+=String.fromCharCode((r&15)<<12|(c2&63)<<6|c3&63);n+=3}}return t}}

Hi All!
Based on @apg314 i came up with this automated scrip that copy one value and past it i othe place in Base 64:

This is exactly what I've been trying to solve. This solution works brilliantly!
It does timeout before it gets to the end of my record set however. 😞
Script exceeded execution time limit of 30 seconds

Hi @Jeffrey_A! Does your record set have more then 50 record?
If so, it is need to implement a 50 run limit.
I did not do that on the script because i only run one line on each time the automatation runs.
I have that limit in others automatations, so it should work on this too.

For anyone looking to convert MapCache fields to latitude and longitude, the inverse holds:
cross posted from https://community.airtable.com/t5/other-questions/convert-address-list-to-geocode-latitude-and-longitude-through/td-p/27854
------
based on work done by @apg314 and @Yourapp from this post, https://community.airtable.com/t5/development-apis/base64-conversion/td-p/103578
I was able to modify the code for Base64 decoding rather than encoding.
Just copy paste code below into a script block and execute to give you a JSON string which contains lat & long
It's a big JSON bundle so you need extra formula fields to strip out lat & long
eg Lat:
This is why I was so careful to understand the scripting context. This is a possible out on the script action side.
so what is the solution to base64Encode an image url in automation script?
I’ve discovered a way to base64 encode an array buffer in the automation scripting environment.
I was trying to base64 the response from a fetch request so I could send the result to another API which required a base64 encoded string.
This is what I got working:
const response = await fetch(url)
const arrayBuffer = await response.arrayBuffer()
const buffer = Buffer.from(arrayBuffer)
const content = buffer.toString('base64')
It’s a little convoluted, but after reaching multiple dead ends as btoa() isn’t supported, I was glad to get something working.
Using Buffer is flagged as a syntax error, but it works, so happy days!
It would be good if more common javascript libraries were supported by the automation scripting environment.
Nice find!
I totally agree that it would be nice if more JavaScript libraries were natively supported.
Alternatively, for those who are looking to get Base64 encoding in a no- code/low-code way that doesn’t require any scripting at all, Make has a native built-in Base64 function as part of its string functions.
If you’ve never used Make before, I’ve assembled a bunch of Make training resources in this thread. For example, here is one of the ways that you could instantly trigger a Make automation from Airtable.
