Paypal API – Security header is not valid (10002)

netheadaches — Mon, 05 Apr 2010 09:14:46 +0000

When integrating the PayPal API you might get the following error returned:

array(9) {
  ["TIMESTAMP"] => string(20) "2010-04-05T09:10:07Z"
  ["CORRELATIONID"] => string(12) "928a82db523e"
  ["ACK"] => string(7) "Failure"
  ["VERSION"] => string(2) "56"
  ["BUILD"] => string(7) "1236498"
  ["L_ERRORCODE0"] => string(5) "10002"
  ["L_SHORTMESSAGE0"] => string(14) "Security error"
  ["L_LONGMESSAGE0"] => string(28) "Security header is not valid"
  ["L_SEVERITYCODE0"] => string(5) "Error"
}

This might have two possible causes:

you are using the wrong credentials (trying to connect to the Sandbox API URL using the Live credentials or vice versa)
you are missing a & character in the NVP string, after the SIGNATURE, PWD or USER keys.

Piece a crap! I’ve spent half a day debugging this error..

So you are trying to convert some avi movies into flv and get rich with your video uploading website.. You’ve tested you upload video functionality and it works flawless, untill some guy comes and say: hey i’ve tried to upload this video and it didn’t work. You run to the Linux console do a log print and you receive this beautiful error:

You run manually the command :

ffmpeg -y -i input_video.avi -f flv output_video.flv

...and the error doesn't dissapear

After googling around reading ffmpeg documentation i found the solution. You need to manually set the sampling frequency like this:

ffmpeg -y -i files/input_file.avi -ar 22050 -f flv files/output_file.flv

Apache not starting – Win32: Apache2 service terminated with service-specific error 1 (0×1)

This usually happens when you do a fresh install of your system and reinstall LAMP.. then you copy/paste your backup configuration files. If you use vhosts (virtual hosts) you may get this error in Event viewer.

It happens because apache tries to access a file in a folder which doesn’t exists. For example,i had setup a virtual host with a custom error log files in a new folder called _logs. After I copied the backup site in the new location I thought I don’t need anymore the old log files so I deleted the whole _logs directory. After a restart I noticed apache wasn’t starting anymore.

What is a “net headache”?

A “net headache” as the name implies is a condition of pain in the head resulted from an annoying error that you read on the computer monitor. This type of headache mostly installs when you do a thing 1000+ times and it worked perfectly and when you do it once more you are served with a stupid error.. You start cursing, your blood pressure increases, you start sweating and you wondering : where da fuck did that come from? At least, this has happened to me right now, after I installed the Apache web server a hundred times before and now it just won’t work..

The “net headache” is even more intense when you are a software engineer, have BS degree and everybody knows you as “the guy who knows computers well” and you have the idea the everything makes sense and there is not reason why it shouldn’t work

Unfortunately there is no pill for this kind of headache.. But there are some solutions. Here is what you can do:

shutdown the damn PC (usually by unplugging) and go to sleep – if you are a true computer addicted , you never do this
grab the monitor and smash it in a wall or something – if you are a true computer addicted, you must’ve done this at least once
do a career turn and start selling brownies
