How to remove the edit request i sent In google docs - google-docs

I accidentally requested edit access in google docs. How to remove edit-request I sent to the owner before the owner knows about the request.
But I don't want this person to see this and to know my new email address. This is really important. Is there any way I can take back this request?

Unfortunately you can't take it back, once you request access you send an email and there is no way to take it back.

here is an easy way to take it back because i sent a edit request and i knew i would get in trouble so you can just hit request acses thing and write a letter saying sorry i sent a request please forgive me

User account email verification links not working

I am having a lot of troubles getting verification emails to work, when a user signs up with parse-server (using MailGun & Heroku).
The verification link sent to the user has this form:
https://myapp.herokuapp.com/apps/.............
but it does not work/
I get this, when clicking it:
Cannot GET /apps/.......
And even if I type only this in the web browser:
https://myapp.herokuapp.com/apps/
I still get this:
Cannot GET /apps/
At one point I was suspecting I could have made some confusion between parse-server-mailgun and parse-server-simple-mailgun-adapter (I am in fact not fully aware of the difference between the two), so I tried both but I still got the same kind of error.
Since, I can reach the point where a user account is actually created and a verification email is sent, I suppose I must have only made some detail mistake in my settings; but I can't see where. Any help or relevant hint from some experienced person would be highly apreciated.
In case someone think I should share some code because the explanation above is not enough, please tell me what you need to know to clarifly my point. And I will provide the necessary information.
You should see your publicServerURL to https://myapp.heroku.com/parse

MassPay API Using NVP returns "Security Header Is Not Valid"

I'm trying to follow the instructions at https://developer.paypal.com/docs/classic/mass-pay/integration-guide/MassPayUsingAPI/#id101DEJ0100A for paying a customer. https://www.paypal.com/us/cgi-bin/webscr?cmd=_profile-api-signature# tells me the API username, API password and and signature. I paste those values directly into my program, and POST those parameters (as well as other parameters) to https ://api-3t.paypal.com/nvp and I get this response back:
TIMESTAMP=2015%2d05%2d06T23%3a58%3a01Z&CORRELATIONID=6eef131f4a296&ACK=Failure&VERSION=2%2e3&BUILD=16566018&L_ERRORCODE0=10002&L_SHORTMESSAGE0=Security%20error&L_LONGMESSAGE0=Security%20header%20is%20not%20valid&L_SEVERITYCODE0=Error
Any tips for troubleshooting what might be going on here?
Thanks in advance!

That error means the API credentials you're using are not accurate. Double the check the values themselves and make sure you didn't miss any characters or add any extra white space on the ends of the values. Also, make sure you're not sending sandbox credentials to the live PayPal server or vice-verse. That's usually what's happening when people run into this.

Nodejs receiving email and redirecting to gmail email address

So i have an website, abc.com. If someone sends an email at support#abc.com i want to receive it at gmail address or whatever address i chose. Then if i reply to that email it in gmail then it should send either using gmail or mandrill. And from of the email should show up as support#abc.com.
This is my first time tackling email. And i have no clue.
So far i understand i need something to take emails in, send emails out, and then there is smtp server.
I get that nodemailer fulfils the role needed by two of the first things..But rest is confusing.
I know this sounds vague but as front end jquery dev i never thought of this much. So be patient and understand like with http protocol i have not much of understanding on this. This question could be many questions however i don't know what those question need to be.

how subscribing to instagram realtime api helps me to get user/media details

I have subscribed to instagram realtime api to receive POST updates for hashtag #sudhir
I am able to get updates to my server this way :
{"changed_aspect":"media", "subscription_id":2935881, "object":"tag", "object_id":"sudhir", "time":1362748903}
I don't find any user related or media related info in these updates. I found in SO that we have to hit their (instagram) endpoints explicitly to get photos/user info, inspite of subscribing to endpoints.
If we have to make request explicitly, then what is the use of subscribing to particular endpoint.?
What is the use of this json data ({"changed_aspect":"media","subscription_id":2935881,"object":"tag","object_id":"nofilter","time":1362748903}) we get in request body of our servlet. ?
Can we use this data in any way to get actual data of user/media ?
Any help or suggestions would be appreciated :)
Nothing useful I'm afraid. Once you have that information you know that something has changed on Instagram's end. You are then supposed to fire off the corresponding request. From your example it looks like you want to then do a tag/recent/ request and filter out anything earlier than the "time" variable.
Not the easiest way to do things unfortunately but they seem to have decided that the hard way of doing things is the way to go.

How can you verify an incoming Twilio sms?

I basically am trying to allow users to post to their blog using a text message. I have a phone number stored for each user, and since twilio sends that information in the post request they hand to my page, I can do a reverse lookup to see which blog to post it to. The question now arises, how can I be sure that the user sent the text? Can't anyone just send post information with someone else's phone number?
I have a couple thoughts about this:
1. Twilio sends your account number in the post, which I suppose isnt known to malicious users.
2. I could respond with an SMS containing a randomly generated code, and have the user send that back. This would effectively triple the SMSs needes do I would prefer the first.
Is number one "safe enough"? Or should I bite the bullet and make a response system as in number two?
You can verify that requests are coming from Twilio. We attach an X-Twilio-Signature header to each request which is signed with your Auth Token (which should be known only by you). Each of the Twilio helper libraries has a function to help determine if the request was made by Twilio or not.
Please see our documentation on validating requests: http://www.twilio.com/docs/security#validating-requests
or our helper library functions for validating Twilio requests: http://readthedocs.org/docs/twilio-php/en/latest/usage/validation.html#validate-incoming-requests, for example.
